This method is superior to that of the   traditional analog filter speed measurement. It can measure the speeds of many projectiles in the antenna. The signal，which was    filtered by the digital filter，has higher signal-to-clutter ratio and noise ratio. Thus，the distance of measuring speed can be  increased greatly. The simulation results show that the higher accuracy can be obtained by using FFT technology.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This paper presents an algorithm based on ?TOA and azimuth measurements of receiver together with the intermittent height information of transmitter for 3-D location and tracking of the moving targets in bistatic radar systems. The location principle of the technique is analysed  in detail. Under the condition of eletronic countermeasure, it is sometimes difficult to transmit the information of transmitter to receiver continuously for data fusion. Therefore it is necessary to study the way of how to use intermittent data. With the help of computer  simulation，the paper evaluates the performance of this algorithm for typical target paths. The fusion technique proposed in the paper is still  within tentative exploration in bistatic research field，so it has much room for improvement in the future.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Recognition of ghosts is a very important problem in multi-sited passive location system based on bearing-Only measurements. In this paper, the  discussion is based on a passive location system which contains a fixed sensor and a moving sensor. A new method for ghost recognition is presented. The approach consists of two phases: the first step is to locate the multi-emitter precisely using extended Kalman filter，Secondly recognizing the ghost with space correlation processing. Computer simulations show that the above recognition method has good  performance when  angle span between two targets is larger than the standard derivation of angle measurements. The accuracy of true target location by this system in multi-emitter condition approaches to the same value as in single emitter condition.]]></description>

Its main cavity uses the structure of adjustable coaxial  height reduced waveguide. This makes the circuit match the diode well. The paper puts stress on discussing the influence of the size of each  part on the characteristic of the oscillator. High Q H<sub>011</sub> mode cylindrical cavity is used as the steady-frequence cavity and metal  materials with different line-expand coefficients for temperature compensation is also used. These improve the frequience stead degree. In  23GH<sub>2</sub>-25GH<sub>2</sub> band, using WT55 Gunn effect diode, the output power of the oscillator is larger than 30mw, the frequence stead degree is 5×10<sup>-5</sup>.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[An active area of research in supercomputing is concerned with mapping certain sums, such as discrete Fourier transforms (DFT) and discrete  cosine transforms (DCT) to multi-processor arrays. This paper presents two kinds of systolic arrays for 2D-DFT using the flow diagram of row-column de composition algorithm. One is a linear array of N<sub>1</sub> processors (if the DFT is N<sub>1</sub>×N<sub>2</sub>), and it takes  O(N<sub>1</sub>N<sub>2</sub>)time steps. The speed-up of this array over the sequential implementation of the row-column decomposition  algorithm on a single processor is O(N)(IF N<sub>1</sub>=N<sub>2</sub>=N). This result is currently optimal not only in PE numbers, but a1so in time cost. The other is a rectagular array of N<sub>1</sub>×N<sub>2</sub> processors and it takes O(N<sub>1</sub>+N<sub>2</sub>)steps. The specdup of it over the sequential implementation of the row-cotumn decomposition algorithm on a single processor is O(N<sup>2</sup>)(IF N= N<sub>1</sub>=N<sub>2</sub>). At last, the paper gives two systolic arrays of 2D-DCT,which are similar to that of 2D-DFT. Furthermore, these systolic arrays can be easily generalized to multi-dimensional cases.]]></description>

The location principle and feasibility of the method are expounded in detail. On condition that an emitter moves linearly at a constant speed, if we can locate and track the emitter only by using azimuth and distance difference without any angle of elevation, the equipment in the receiver will be simplified and the independence of the receiver will be improved as well. Then the algorithm proposed in the paper is of great importance to the practicability of the single observer passive location and tracking system. Performance of this algorithm is evaluated with  the help of computer simulation of three typical target paths.]]></description>

The PNN implements the statistical Bayesian strategy by computing a joint probability density over all  input parameters to match a group of candidate data classes, the sorting is accomplished by assigning the inputs to most likely group with highest probabílity density estimate. Then the prospect of applying the self-organized PNN to ESM pulse data sorting will be shown，and a  system including self-organized PNN and pulse repeating interval sorting will be discussed under the limited conditions of the sorting after lots of emulated experiments.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The detection of transient signal using wavelet transform (WT) has been studied recently. A new method for detection of transient signals with  unknown waveforms and arrival times is proposed. The Mexican hat function is chosen as basic wavelet，and combining with the prior information  of transient signal，the values of dilation and translation parameters are selected appropriately. As a result transients whose waveforms partially overlap in time at a very low signal-to-noise ratio can be recognized in the WT domain. Using Monte-Carlo simulation，the structure of the proposed detector is discussed and its performance is evaluated.]]></description>

It is a highperformace system with high throughput rate and short delay. In order to meet the high speed requirement，the demanded real-time and concurrency in the main computation is first analyzed，then a decorrelation procedure for wavefront processing is proposed. Based on  the several subtasks in wavefront computation，data acquisition，slope computation and wavefront reconstruction are conducted in pipeline. The delay is reduced greatly by the utilization of image aquisition time and the foundation of pepeline.]]></description>

In this paper，a new method of detection based on fractal characteristics of sea-surface scattering is proposed. By comparing the difference in the fractal dimension between the sea c1utter and the  echoes from a target，an effective detection of the radar ship targets can be realized. In order to test this method，we use the real radar returns of ship targets for detection and a better result has been achieved.]]></description>

The first is a sensor/target class which is more easily extensible than many types of radars and targets. The second is a tracking algorithm class which allows a series of tracking algorighms to be used. The third is a fusion tracking-control display class that allows easy access to many of the performence measures for radars and evaluation and debugging of the tracking algorithms. At the same time, netted-radar tracking prototyping system has been developed on computer network platform of distributed Client/Server system. The prototyping system can efficiently track multiple-aircrafts in real time, and attain strict tracking accuracy. Furthermore the prototyping system allows achievment of some growing. reconstructing and reconfiguration capabilities in case of failure of one or more of the radars.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Stochastic temporal reasoning in situation assessment (SA) is very important in many applications. The approach based on Maximun Likelihood Estimation (MLE) treats the unknown temporal variable as a constant, which doesn't use a priori information and generates a larger/estimate variance. In this paper, the relation model of known temporal information and unknown temporal variable has been established, which can also be used for MLE-based method. In the model, the reasoning algorithm about time instants has been derived from treating the unknown temporal variable as random variable and introducing MAP estimation into temporal reasoning. The performance analysis between MAP-based method and MLE-based method shows that under some conditions, the estimate variance of MAP-based method is lower than that of the MLE-based method, and we have given these conditions in experiments.]]></description>

The layer here can take 0 value or an integer L. Layer 0 means that no target can find its association data from current returns. Layer L means that L targets can find their association data from current returns. Our layered construction method in the paper is recursive and of independence among layers, so it can also be implemented in parallel structure. Comparative analysis of the method with relative methods in other references and the corresponding computer simulation tests and the results are also given in the paper.]]></description>

The other method finds the structures at a coarser scale, and then focus on finest scale step by step to derive the thresholds.

First using Zero-Crossing-Based 2D Edge Detector we can get the two-value edge graph; after edge linking and giving each planar curve its orientation space representation we can get the orientation curves. Based on the multi-scale wavelet transform of the orientation curves we can utilize the information of local maximum positions to detect and locate the corners. Experimental results with some synthetic and real images show that this algorithm has high precision and stability of the corner detection and location.]]></description>

Variable step-size LMS algorithm (VSSLMS) which uses auto-correlation of errors can provide fast convergence, eliminate the influence of independent noise, thus give good performance in non-stationary environment. But it can not perform well with input which has large dynamic range. This paper combinates their advantages, and the new algorithm can perform well both in the environment of low SNR and the environment with large dynamic range of input.]]></description>

A way of improving SCR(Signal-to-Clutter-Ratio) is presented by linear integration filtering in polarization domain. With the intrinsic high-resolution characteristic of wide-band waveform, one-dimension range profile of radar target can be obtained. The number and distribution of intense scatterers in radar returns can be estimated. A polarization target detection method is presented based on the correlation of these intense scatterers in various resolution cells. SCR can be improved efficiently and so can the detection performance of radar. The experiment results show that this method is a very effective detection strategy for extended targets.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new adaptive time-frequency Inverse Synthetic Aperture Radar (ISAR) image analytical method is presented, which combines the ISAR processing with the time-frequency analysis algorithm-Adaptive Guassian Representation(AGR). This technique uses Guassian basis function to adaptively parameterize the data. And as a consequence, the point-scattering and dispersive-scattering mechanisms can be readily separated based on the width of the Guassian bases. Applying this transformation to range and crossrange axis of ISAR image can extract the frequency-dependent and the aspect-dependent features of nonpoint-scattering centers respectively. The method is tested by using simulation data and real data. The results show that it is a robust tool to post-process ISAR image. And it can provide additional information about the pointlike and dispersive scatting mechanisms that can be useful for ATR.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In wireless system where multiuser detection techniques may be applied, the ambient channel noise is known through experimental measurements to be decidedly non-Gaussian. This paper consider the problem of adaptive robust detection of direct-sequence spread-spectrum(DS-SS) signal in the presence of unknown correlated SS interference and additive non-Gaussian noise. Many efforts have been made and most of them have two major problems:the first, explicit a priori knowledge of the underlying noise statistics is generally not available in a realistic scenario; second, computational complexity must be taken into consideration. From traditional subspace tracking techniques, we derive a robust method with low computational complexity. Analytical and simulation results show that the proposed robust techniques offer significant performance better than the normal subspace tracking methods in impulsive noise.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new scheme of contrast enhancement of infrared image via wavelet transform is proposed. By means of wavelet transformation of the low contrast infrared image, its distribution of multiscale gradient can be achieved. We improve image contrast by modifying the modulus of the gradient image on multiple scales rationally and enlarging its dynamic scope in scale space directly, and we can control noise magnification. Experimental results demonstrate this method is better than histogram equalization under this circumstance.]]></description>

The circuit configuration of the proposed approach is simple，its dynamic response speed is fast，and its detection precision is high. It can detect any current component in distorted current or the sum of the harmonic and the reactive currents.

This system, using a PC as the control unit, can be used to get data from three different kinds of radar, and implement data acquisition through six channels, and store large amount of data. In order to realize high speed and large amount acquisition, we use S5933 as PCI interface, using the high transfer speed of the PCI bus,satisfying the required data transfer rate between the control unit and the acquisition unit. At the same time we use dual-port RAM to provide continuous acquisition；and use FPGA to implement the control circuits, simplify the circuit board design and improve the flexility of the design. In order to ensure the security and stablity of the whole system,we implement the software system under Windows NT operating system]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This paper discusses the design of complex coefficients FIR filters in the complex Chebyshev sense. One way to solve this problem is to  first formulate the complex Chebyshev approximation problem into finite linear programming through discretization, and then simplex method follows. But it has been thought that this method involves too much computation cost, converges slowly and it is  applicable only for designing real coefficients FIR filters. Here a new algorithm is formed, which is a variant of the simplex method. It exhibits good convergence, low computation effort and can be used to design complex coefficients FIR filters. It proves equal to the algorithm formed from the dual of semi-infinite linear programming. An example is presented in the end.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Linearization of power amplifiers has become an important issue, with the advent of linear modulation methods in mobile communication. The predistortion is the most commonly used technique for linearizing an amplifier in order to improve the linearity degree of amplifiers and reduce the out-of-band emission of the transmitter. An adaptive predistorter for linearizing a power amplifier in a mobile transmitter is studied utilizing a complex spectral convolution. Analytical and simulation results show that a complex convolution method which requires no additional local oscillator or phase reference can be used to measure the out-of-band power and utilized the scalar quantity to update the predistorter's coefficients, in order to minimize the out-of-band power.]]></description>

In this paper the theory of normalized scheduled data flow graph(NSDFG) which has the clear physical meaning is discussed. Based on the node movements in the NSDFG, the intrinsic mechanism of legal pipeline scheduling is studied in detail. The study proves that from any initial point in the design space any legal scheduling can be searched through the legal node movements. The self-contained set of legal transformations derived in this paper provides a key for the search-based algorithms to be applied in pipeline scheduling.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Digital watermarking is a key technique for protecting intellectual property of digital media. Similar to the noise pollution, watermarking process may induce image degradation. Since image quality is a determinant of its worth, it is significant to adjust the parameters in watermarking algorithm to satisfy specified quality requirement. Based on the Laplacian distribution model of AC DCT coefficients, we deduce theoretical relationship between the scaling parameter in a typical watermarking algorithms and signal to noise ratio (SNR) or peak signal to noise ratio (PSNR) of watermarked images. Thus the scaling parameter can be estimated according to the assigned image degradation grade. Experimental results demonstrate that the estimation has enough accuracy.]]></description>

First the hidden Markov tree(HMT) model in wavelet-domain is established. The parameters can be estimated by EM algorithm.Then SAR image's statistical property is studied, the multiple speckle noise of SAR image can be approximate as white Gauss addition noise under the local area. The wavelet coefficient of signal can be estimated by minimum mean-square estimate(MMSE). Applying this method to simulated image and real SAR image, the result shows that this method can effectively reduce speckle noise, while keeping image details.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This paper presents a novel method for distance measurement by multi ultrasonic arrays within the Direct Sequence Spread Spectrum (DS-SS) framework of the communication system. In view of the results of ultrasonic distance measurement simulation, it can be seen that the system design considerations, which is ground on the demodulation of BPSK signals by digital correlation and the adaptive equalization of receiving channels by means of Least-Mean-Squares algorithm, lead to strong restraint of the effect of disturbance in many cases, such as the phase error of local carrier used for coherent demodulation, the jam of multipath channels, and the random drift of the gain and phase in receiving channels, hence improve greatly the signal-noise ratio and the resolving power in ultrasonic orientation system accordingly. Furthermore, since the principle of the ultrasonic measurement system adopted here is based on spread spectrum with pseudorandom sequence codes, it is easier to realize of the Code Division Multiple Access (CDMA) by allocating different codes at different testing areas, so as to distinguish different signals transmitted by different ultrasonic transmitters/receivers, which will extend the measuring scope of the system. Thus it can be said that the methods considered in this paper has expansive prospect in the measure and control field for practical purposes.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Considering the problem of the maneuvering target tracking in the nonlinear system, this paper first proposes a modified algorithm based on “current" statistical model. Then a converted measurement Kalman filter is applied to tracking the target. Simulation results show that the algorithm improves the tracking performance obviously for the poor-maneuver or non-maneuver target, meanwhile it retains high tracking performance for the strong-maneuvering target.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[We present in this paper the production of beat wave using a single L-band travelling-wave tube (TWT) amplifier. The beat wave was first generated in a primary source using power synthesis method, then injected into a TWT amplifier to obtain relatively high power output. This approach is initiated to provide practical beat wave radiant source for high power microwave (HPM) effect research. Experimental results demonstrate that for 1～2GHz carrier frequency, it is quite practical to produce beat frequency ranges from 1MHz to 900MHz at 10kHz repetitive rate using one TWT amplifier. The output parameters of the beat wave are readily adjustable in terms of varying the feeding frequency components' power levels. The production of beat wave using single TWT amplifier takes advantages over some conventional methods since the beat wave can be formed in low power, low cost microwave sources. This method has been successfully used in certain electrical system HPM vulnerability effect experiments.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Generally speaking, the spectrum of feeble signal folds the spectrum of sea clutter, and the location discrepancy between the target and its surroundings is small. So it is difficult for the classical processing in the frequency domain or space domain to detect the feeble signal in the ocean. This paper presents a new approach with Wigner-Ville distribution based on the linear frequency modulation signal detection in the ocean whereas WVD has the time-frequency local characteristic for LFM signal. It studies the difference between the new approach and the classical frequency approach for signal detection using the real data of the sea clutter collected by the radar in the condition of the several signal-clutter-ratios. The results show that the new approach has evident advantages compared with the classical approach. When the signal-clutter-ration is -14.3dB, it still detects the target effectively.]]></description>

The method of moments in conjunction with Lanczos technique is applied to predict the mono-static radar cross section (RCS) of an arbitrarily shaped two-dimensional dielectric cylinder. The electric field integral equation (EFIE) in the dielectric cylinder is established firstly, and then EFIE using the method of moments is changed into the matrix equation, and the electric field in the dielectric cylinder is obtained by solving the matrix equation using Lanczos technique. It is observed that the Lanczos technique can result in considerable CPU time saving.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new way for detecting the targets through images is proposed, and then using it, a new method for extracting texts is proposed. This method can be used not only to index the image database and the video, but also to invert the documents in papers to electrical text format. It can be divided into two steps. In the first step, the candidate regions, which can include texts, are extracted, in the second step the candidate regions are verified by analyzing the distribution of gray value of the scan lines by Hough transform method. The shape of the extracted regions is also pruned to contain texts compactly. This new method can be used to extract texts with different sizes, orientations,  fonts and  gray values or colorsBecause all operations of the new method are based on pixels, the new method can be realized by hardware easily. The experiments we have done justify its validity.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In the application of GIS, there is a need to manage spatial data. For this purpose spatial database systems are designed to be full-fledged database systems with additional capabilities for storing, retrieving, manipulating, and querying spatial data. But there are many difficulties to manage spatial data using spatial databases, such as numerical robustness and topological correctness. To solve these problems, we introduce some new concepts about Regularly Spatial Discrete Domains (RSDD), RSDD-based Primary Object (RPO), RSDD-based Object (RO), and defined the spatial data types and their operations over RSDD. As in a computer system, it is feasible only with limited precision, i.e., over a finite, discrete, and homogeneous grid, this strategy is ad hoc suitable for correct finite-precision implementations of geometric algorithms.]]></description>

Accuracy of these algorithms are compared by a covariance analysis method, and a conclusion is drawn that they can all obtain LMMSE (Linear Minimum Mean-Square Error) estimation under some assumptions. Other performance of these algorithms, such as computation cost and flexibility, is compared by Monte-Carlo simulation. Results show that augmented method based on information filter has the lowest computation cost and highest flexibility, augmented method based Kalman filter and pseudo-sequential filter have higher computation cost, and the two combined measurement filters are less flexible because they demand that sensor measurement matrixes satisfy some additive conditions. These conclusions are valuable in practical engineering applications.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Tatical data link system is an information system combining communications, navigation and identification, intended to exchange surveillance and command and control (C<sup>2</sup>) information among various C<sup>2</sup> platforms and weapons platforms to carry out varied missions of each service. Tatical data link terminals operate in the 960～1215 MHz band, which is reserved on a worldwide basis for the safe operation of aeronautical radionavigation equipment. The tatical data link system must be planned carefully before the operation. However several restrictions or limitations must be placed on operations. The typical constraints among different platforms are discussed in this paper. Then the tatical data link planning problems are modeled. Finally a greedy algorithm is described.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[SAR images generated on the basis of FFT suffer the poor resolution. In super-resolution algorithms of SAR/ISAR image the modern spectral estimation technique is usually used, such as Minimum Variance Method (MVM), AR model, eigen-vector, MUSIC and maximum entropy, to improve the resolution of the image. High-resolution spectral estimation of finite length sample is considered an underdetermined problem. In the framework of Bayesian criteria,  a prior probability density function (pdf) of the spectra is included as a regular term in the cost function for MAP estimation. To improve the efficiency of calculation in 2-D case, fast algorithm is derived. The better resolution is achieved by the method while the method is applied to SAR image peak feature extraction.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A kind of joint frequency-DOA spectrum estimation  using virtual tapped-delay-line array is proposed, which generalizes the classical subspace algorithm to two-dimensional space-time domain. The proposed method has three advantages: firstly, increasing the freedom degrees of the corresponding array leading to an enhanced ability to identify much more emitters; secondly, almost free from estimation bias due to the divergence of signal wavelength from what the array size expresses; thirdly, estimating not only the DOAs but also the frequency domain characters of emitters. The obtained characteristic of emitters is more integral.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Topological relationships are important spatial relationships, and used in numerous practical applications that involve spatial query and spatial analysis. So it is essential to use formal methods to identify and define a complete and mutually exclusive topological relationship set that can be embedded in spatial query languages. Now, the topological relationships that have been defined cannot represent the topological relationships between the two complex spatial features arbitrarily composed of points, lines and/or polygons, thus the researches on topological relationships are not complete. We introduce the formal definition of mixed geometry, and define a topological relationship set: ｛disjoint, touches, within, crosses, overlaps, contains, equal｝.The set, extending the definitions of topological relationships in ‘OpenGIS Simple Features Specification for SQL’， is complete and exclusive, and can be taken as a unified framework to define topological relationships in spatial query languages.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Fast algorithms of code acquisition and tracking for DS/SS are presented based on software radio. Code acquisition can be done via calculating the cycle-correlation between received IF signal and local matched filter, using the auto-correlation's sharp characteristic of PN sequence. Two fast algorithms for cycle-correlation are presented. Their correct acquisition probabilities and average acquisition times are analyzed. Finally a simple algorithm of code tracking and its precision are presented. The correctness and validity of these algorithms have been tested by simulation and experiment, and they can be used especially when the SNR is very low and the size and power of the instruments are strictly limited.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Statistical parametric mapping (SPM) depends on the general linear model(GLM) and the theory of Gaussian fields to some extent. But the disadvantages of the GLM are related to the fact that these assumptions outlined do not fairly represent the fMRI data. Also, hemodynamics and distributed patterns of the brain activity may not be well modeled by the GLM regression framework. While, the independent component analysis(ICA) does not provide the investigator with a significance estimate for each component activation, which may discourage experimenters from attempting to interpret the results. The paper proposes a method which combines some of thebenefits of ICA with the hypothesis-testing approach of the SPM. Experimental results demonstrate that the proposed method is effective for detecting the activations resulting from a motor task.]]></description>

When GPS data is displayed on a GIS map, logically the vehicle point should be displayed on the roads. But because of the effect of errors, there are always warps between the true vehicle point and the displayed point on the map. It is necessary to correct these warps. An algorithm—Buffer Linear Abstraction Algorithm (BLAA) is put forward. This algorithm improves a former algorithm—Linear Abstraction Algorithm (LAA). Experimental result shows that BLAA has high precision, and at the same time it is more efficienty.]]></description>

But these process-gains usually cannot satisfy a low bit-error-rate if the signal-noise-ratio of input signal is very low. In a DSSS system based on the software radio, the receiver can despread and demodulate the IF signal simultaneously. It can be proved that this method can get a higher process-gain when the sample rate meets a certain condition, so it can be used in a low signal-noise ratio system.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Topological relationship is a very important spatial relationship in geographical information systems (GIS). During the past decades, many models that distinguish topological relationships have been proposed. But these models cannot distinguish the topological relationships between heterogeneous geometrycollection objects, which are composed of different dimensional geometries. We introduce the formal definition of mixed geometry and regularization rules. Base on the spatial model and Dimensionally Extended Nine-Intersection Model (DE-9IM), we propose a topological relationship model—Integrated Dimensionally Extended Nine-Intersection Model (IDE-9IM). The model can distinguish not only the topological relationships between single points, lines, areas, and/or homogeneous geometrycollection objects, but also the topological relationships between heterogeneous geometrycollection objects by considering the whole objects and the components of the complex objects. So IDE-9IM can be taken as a unified model of distinguishing topological relationships between arbitrary spatial objects.]]></description>

The bloodstream is rendered by the  metaballs method. During the simulation, only the dynamic simulation of the leading end of the bloodstream is considered while the rest of the bloodstream is rendered statically. This combination of dynamic simulation and static rendering can reduce the expense of computation and make the model more real and more computationally efficient for real time animation.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The principle of micro-zooming is analyzed in the spatial domain. Micro-zooming is the method that changes imaging focal length of the optical system gradually to obtain a series of images of the same scene with different amplified multiples, and reconstruct a high resolution image through these images. It can be used to realize superresolution imaging of opto-electronic imaging systems. Micro-zooming imaging can be equivalent to change the area and position of the sensor element's corresponding object radiance distribution region, which are related to the magnification and the location of the sensor elements respectively. So the spatial model can be established and the relationship  between the  observed images and the ideal high resolution image can be given as linear equations. The high resolution image can be obtained by solving the equations. The experiment of the superresolution imaging of area-array CCD by micro-zooming is  described in the end of the paper. It denotes that the resolution of the image increases markedly.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[MFCC can express speech spectrum more accurately at low frequency, so MFCC is a good method to express the spectral envelope in voice conversion; A new and efficient algorithm for MFCC is proposed. At first, the staircase envelope is obtained through harmonic extraction, then the staircase envelope is transformed by Mel frequency scale, at last the MFCC coefficients are extracted by cosine transformation. The algorithm can be realized easily, and the result is good.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The direction of the motion which blurs the image can be dealt with as unchanging during the short exposing time. If it is identified, the blurred direction can be rotated to the horizontal axis, and the image restoration can be worked out easily in one dimension. An excellent simple model for imagery statistics is that of a spatially isotropic first-order Markov process. The autocorrelation of the original image and its power spectrum are assumed to be approximately isotropic. The motion blurring decreases the original image's high frequency contents in the motion direction. Thus, a derivative of the image in the motion direction would suppress more image intensity than a derivation in other direction. Then the motion direction is identified from the blurred image. The derivation matrix is the key for the identification. We select a propriety unchanging step for the direction derivation, a 3×3 direction derivation matrix is then constructed by using the double line interposition. This 3×3 direction derivation matrix can help to identify any motion directions of the most motion blurred images with high precision. It is steady-going.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Based on the signature analysis of wideband echo from the ballistic missile, a novel method is proposed, which can extract the features of the moving target. High-resolution radar echo is processed by STRETCH technique and range profiles are obtained. By observing the periods of the target length variant, the frequency of nutation is deduced. According to the location of the rangeprofile in imaging windows, the range between the radar and target is estimated. After the range shift between the two adjacent rangeprofile provided by envelope correlation algorithm,the target velocity is estimated by computing the time difference between the adjacent two mixers. Simulation results show the effectiveness of the method.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Promoter identification is an essential task in the research of transcription regulation, but computational prediction of promoters has been one of the most elusive problems despite considerable effort devoted to the study.  A new prediction algorithm based on the combined features for E. coli σ<sup>70</sup>promoters is proposed. According to their location, all promoters can be classified into two classes: promoters in non-coding regions and promoters in gene regions, and will be processed respectively. In each region, the features of primary sequence，including 1 content feature、5 signal features and 4 structure features, are combined and defined as a 10 dimensional vector, then the vector of combined features is further used by quadratic discriminant analysis to predict the potential promoter regions. The algorithm has been trained and tested on E.coli σ<sup>70</sup> promoter dataset by the jackknife method. The average prediction accuracies for “non-coding” promoters and “coding” promoters are 86.7% and 82.4%, respectively. The results indicate that our algorithm outperforms most of the existing approaches based on several performance measurements. Furthermore, algorithm framework is extendable and can accept more new features to improve the prediction results efficiently.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A novel power conditioning circuit for flux compression generators (FCG) to drive high impedance loads is presented. FCG usually has very low impedance, and power conditioning is necessary with high impedance loads. The traditional power conditioning scheme uses a pulse transformer and sometimes an additional capacitive pulse forming line (PFL) to improve the output waveform, making the system bulky. The paper introduces a circuit without transformers, using PFL as an inductive energy storage unit. This scheme has the advantages of simplicity, compactness, and easy insulation. Numerical simulation is shown to prove the concept. By using this circuit FCG will have wider applications.]]></description>

The algorithm uses cross-correlating function between the  succeeding pulse in the cluster to estimate ambiguous frequency of the cluster and select the same ambiguous frequency between the succeeding cluster of pulses to solve ambiguity to acquire the relative frequencies. Because these relative frequencies include the same ambiguity, the filter algorithm can be used to estimate the Doppler frequency rate between the clusters of pulses. The relative frequency and Doppler frequency rate estimation accuracy is high, and the process of solving the ambiguity is simple. The performance of the algorithm is effectively demonstrated by the computer simulation and ground test.]]></description>

Secondly, considering the real distribution of the targets as the users' need for information, we use Kullback-Leibler distance in the information theory to measure the difference between the probability distribution of the targets and the users' need for information. Finally, a situation awareness curve of different S&R systems is derived and the impact analysis of the transmission and processing delay on the curve follows.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Effective data source selection strategy is one of the important issues of the spatial information retrieval. This paper proposes a method to select data source based on spatial scale semantics. The method determines the data source set for the distributed query plan fully considering the human vision features, filters those data sources which don't contribute to the final result. Through prefetching the simplified representation of data sources, the method can further  reduce the overall cost of a query. The experiment shows that the proposed method has favorable performance both in small and large size query.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new texture feature extraction method using Local Walsh Transform (LWT) is presented. The definition of LWT is given. The statistical properties of LWT coefficients are analyzed. The texture discrimination performance of the moments of LWT coefficients are investigated. Detail examinations reveal that the LWT coefficients of the natural texture images usually do not yield to Gauss distribution, their even-order moments have high texture discrimination performance, while their odd-order moments have low texture discrimination performance. Hence, the even-order (2<sup>nd</sup>, 4<sup>th</sup>, 6<sup>th</sup> order) moments of the LWT coefficients are selected as texture features. Compared with the other texture features defined by Haralick<sup>［1］</sup>,Wang and He<sup>［2,3］</sup>, Hui Yu<sup>［5］</sup>, the texture features we present have the best texture discrimination performance.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Some problems in the application of spatial information, such as distributed enormous data, heterogeneous format, complexity of processing and intensive computing have been obstacles to realize wide sharing and integration of spatial information. By taking grid technology and web services as its technical core, spatial information grid (SIG) shares and aggregates the distributed enormous spatial information resources to implement dynamic integration and collaboration. Based on building open seven-layer application architecture of SIG, we put, in the research, emphasis on SIG service composition. A novel service composition model named service/resource net (SRN) is proposed based on Petri net and graph theory. Moreover, an innovative service selection model (SISM) is presented to implement the dynamic service selection in the process of SIG service composition. In accordance with the application requirements of the national geological survey, an application example of ground water evaluation is given and the validity and usability of SIG are verified.]]></description>

It is based on the fact that different class should have its own representative feature set, and it realizes feature extraction and classification in one step while preserving as much separability. It also possesses the advantages of PPCA model, which is more effective to high dimensional data processing. Applying the method to simulated data and real data shows that it can achieve better results compared with the method that applies PCA to all data without differentiation among classes.]]></description>

We employ the positioning system of the commercial mobile communication network as the network based positioning. The local sensors used here are internal sensors, such as position and velocity sensors of the vehicle. In order to reject random noises in the global and local position sensing, the variable-dimension Kalman filter is employed to fuse the information from different sources and estimate the position of the vehicle. The performance of this new method has been verified by simulations on the tracking of maneuvering vehicles.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To solve the problem of the store and transmission of vast DEM data, an efficient compression algorithm for DEM data is presented. A technique based on the lifting scheme is designed to construct the compactly supported wavelets whose coefficients are composed of free variables. By properly selecting the coefficients of the 9-7 wavelet filter and being associated with the lifting scheme, an efficient approach via wavelet for DEM data compression is developed. The integer wavelets based on the lifting scheme only used integral addition, integral multiplication and shift, so it can be fast and easily realized via the hardware. When t=1, the integral wavelet filters approximately have the same complexity as integer wavelets 5-3, but preserve approximate quality of the compressed DEM data with the well-known CDF9-7 wavelet filters. The experiments show that the method can compress DEM data very well. Provided that the terrain figure and hypsography are maintained, the DEM data's compression ratio is 4096 and PSNR>34DB.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new algorithm for image enhancement based on the dyadic wavelet transform is proposed aiming at minimizing the image noise while amplifying the image feature. By making full use of the shift invariability of the dyadic wavelet transform and correlation of the wavelets coefficients from different scales, the proposed algorithm can efficiently alleviate the amplification of the noise and distortion of edges, which are the most difficult and common problems in image enhancement. Furthermore, the enhancing strategy is highly adaptive and thus applicable to images from many sources. The results of experiments are also given, which show that the new algorithm performs better in both de noising and image feature enhancing compared with the existing multi scale algorithms.]]></description>

The amount of computations is greatly reduced by holding the dimensions of the feature matrix compared with that of the former methods in the presence of a long record. Due to FOMC's auto suppressing Gaussian noise, the SNR threshold is reduced and the precision of the parameter estimation is improved. Simulation results show that this method is of better performance and higher efficiency than the former methods in colored Gaussian noise.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Contraposing the shortcoming of “flooding schedule” in the standard LDPC(low-density parity-check) decoding algorithm, this paper presents a serial decoding schedule， which shuffles the massage passing schedule of standard LDPC decoding algorithm. The new schedule processes and propagates messages according to a serial update order of bit nodes. Each bit node receives check messages and sends bit messages in the same iteration so that the updated messages could join iterative process immediately. As a result, the convergence property is improved. Simulation results show that, under the same decoding complexity, the proposed version is optimal in the sense of MAP decoding and converges faster than the flooding schedule. Meanwhile, it keeps the appropriate decoding complexity, so it is a good method that can offer better trade-offs between performance and complexity.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[As one of the key techniques in inverse synthetic radar (ISAR), autofocus is to eliminate the phase errors caused by the target radial motion. The maximum likelihood (ML) estimation of phase errors was derived form the ISAR signal model, and an autofocus algorithm based on the ML estimation was proposed. In the algorithm, the phase gradient algorithm (PGA) was performed, and the signals of multiple scatters on a few range bins were utilized. Hence, the scatters might not be well isolated, and the troublesome phase unwrapping was avoided. Moreover, the algorithm also eliminated the accumulation errors in the phase error estimation. The imaging results based on the measured ISAR data demonstrate a good performance of the autofocus algorithm.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A new incremental clustering algorithm is proposed in this paper based on the relativity principle, which means that the similarities of objects in the same cluster is higher than those among different clusters. This approach not only inherits the advantages of absolute density based algorithms which can discover arbitrary shape clusters and are insensitive to noises<sup>［1］</sup>, but also efficiently solves the following common problems: clustering results are very sensitive to the user-defined parameters, reasonable parameters are hard to be determined, and high density clusters are contained fully in coterminous low density clusters. With this approach, incremental clustering can also be supported effectively by defining the affected sets and seed sets of the updating objects in this approach.]]></description>

These data can be used in new genes identification，analysis of genes express patterns and the annotation of genomes, which may provide the reference standard for experiment design and result analysis of transcriptome experiments. Since the alternative splicing of eukaryotic genes have found to be universal and play an important role in physiology and pathology, systematic analysis of alternative splicing is becoming a new hotspot of functional genome research. Facing the immense and exponential increase of experimental express data and more new genomes getting sequenced, there is exigent of the strategy which can handle transcriptome sequences in large scale and automatic way. We elucidate the algorithms, the computing requirements and programs in different transcriptome sequences analysis systems and propose a strategy more suitable for large scale analysis of alternative splicing.]]></description>

A new conception based on biological vision principle, called Edge Tag, was introduced to describe the edge structure. After the correlation calculation between two Edge Tags, decision rule was made to locate the outline of changed area. The Edge Tag based change detection was robust to illumination variance and registration noise. Experiments on simulated data and real images verified its superiority.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Although a large number of researches have been undertaken in the area of transcription start site (TSS) localization, the problem of TSS localization has not yet been fully resolved. According to the previous promoter prediction algorithm, a new sliding window based computational localization method for E. coli TSSs is proposed. The TSS-likelihood scores of each possible position in genomic sequences are calculated by the window classifier which is improved by introducing the composite motif model in the training procedure of original promoter classifier. The distribution of distances between TSSs and translation start sites (TLSs) is also utilized to calculate the TSS-position scores. Localization results are achieved from the final score profiles which combine TSS-likelihood scores and TSS-position scores. The test results on E. coli dataset show that the method can find the putative TSSs and decrease the number of false positives efficiently.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Track association has been recognized as one of the major problems in distributed multiple-radar multiple-target tracking systems. Tracks formed on the same targets by multiple radars may differ due to misalignment or bias error. So the traditional features, such as target position and speed, cannot be reliably used for track-to-track association. The information of relative positions among targets, however, is found to contain special characters and can be extracted as target topology vector of reference dynamically. Applying fuzzy pattern recognition to analyze the similarity of vectors or patterns can set up the criterion of association and provide prior information for alignment. Simulation results show that the proposed algorithm is effective to solve the association problem under the condition of inter-radar bias and robust to the random errors.]]></description>

Furthermore, ILS (iterative least-squares) is also proposed to fuse AOA measurements from two ESMs. Experimental results show that the location accuracy of the radar emitter can be improved effectively by this AOA fusion algorithm.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Analysis of short sequence motifs is an important component of gene sequence analysis. Information of motifs is usually used for identifying biological signals. However, the number of short sequence motifs is very large. If all of them are used for signal identification, there will be too many parameters, thus covering the main characteristics of the signal. To find out the key short sequence motifs for signal identification, in this paper, a stepwise strategy was adopted to rank motifs by their information gain. As a result, the motifs were selected orderly for signal identification. In so doing, good results were achieved with fewer motifs. Consisted with the selected motifs, maximum entropy model was used as the approximation of the true distribution of the signal sequences, thus realizing the identification of a given sequence. Finally, the model was used to identify 5'splice sites, and approving experiment results were achieved.]]></description>

It, in terms of the energy concentricity of the image's wavelet coefficients, selected the parts with concentrated energy to construct the feature vectors, which include most of the edge, texture, luminance and structure features. As there is no limit to the distribution of the image feature information, the method can be used in many kinds of image feature extraction, thus solving the problem of feature illegibility with which the single-feature extraction is confronted. In the experiment, normal white noises with different ranges were added to the images and the result approves that the feature vectors are robust to noise.]]></description>

To avoid those complicated processes, the reference images are first classified into primary reference image and subordinate reference image according to the distance between the reference viewpoints and the novel viewpoint. Then the global optimization problem of view synthesis is transformed from the depth field to disparity field, using a process of nonlinear rectification and multi-epipolar technology. Finally, the novel view is synthesized from the image sequence without matching and calibration.

However, recent researches still focuses mainly on 2D representation while the existing 3D methods are always embarrassed by their low computation speed, a new hardware accelerated 3D representation method was put forward in this paper. Based on the constructed 3D data field of EM loss affected by environment, a hardware accelerated algorithm was designed to extract the isosurface for building the 3D radar coverage model. Then the model was represented into digital battlefield. In the experiment on popular PC and for typical Radar, the 3D radar coverage affected by terrain and atmosphere was vividly visualized in time. The result has overcomed the implicity of 2D method and the slowness of 3D method, thus providing excellent decision and sense supporting for users.]]></description>

RD algorithm was deduced using quadratic model. In squint side-looking situation, quadratic model may have inignorable error. The error mainly can influence azimuth compression. In order to suppress azimuth sidelobe, imaging using azimuth compressing function according to beeline model was studied. For preserving image phase, right azimuth compressing function should be used to avoid destruction of the phase.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In the presence of sea-surface multi-path，due to the interference of multi-path reflection, the measurement of a low elevation target by monopulse is often greatly affected. So off-axis tracking technique was adopted generally. By means of the analysis based on the model of multi-path reflection environment，both specular reflection and diffuse reflection were considered. Expression for the average bias in the mono-pulse ratio due to specular and diffuse reflections and the noise in the radar channel was derived.  Algorithm was combined with bias compensation so as to adapt to the elevation measurement of off-axis tracking targets in the presence of sea-surface multi-path. This is aimed to avoid the disadvantage of both techniques employed here. Throughout the simulation in some scenarios, the results show that the method combining the two algorithms together can improve the precision of low-altitude target elevation measurement. Then it was applied in the extraction of postal data of off-line cruising flying object's elevation measurement, and a comparison was made with real time data elevation measurement by actual radar system. The results indicate that this method is effective and feasible in the off-line elevation extraction and it can remarkably improve the precision of elevation measurement]]></description>

With this method, computation of interpolated function was transformed to tabulation of the interpolated function, and the maximum error was presented. Additionally the derivative operation in translation operator was placed on the outermost, which reduces original (K+1)(2K+1) times operation of FFT and IFFT to one time. Consequently the cost associated with the computation was decreased. Two examples were presented to demonstrate the accuracy and high efficiency of the improved algorithm.]]></description>

In this paper, based on the sliding windows, an approach is presented for the multiple range aggregation queries over spatio-temporal streams. Time fragments were employed to describe the overlaps between sliding windows and spatial fragments for the overlaps between spatial range predications. Then a technique was proposed to partition the streams into different spatio-temporal fragments without any overlaps. The final query results could be captured from the temporary query results over the spatio-temporal fragments. Experimental result shows that our approach can substantially increase performance of the multiple range aggregation queries over spatio-temporal streams.]]></description>

In this paper, the dither demodulation filter was analyzed and its influence on attitude algorithms was researched. The formulas of optimized attitude algorithm were derived to match the response of the filter. The optimization technology did not complex the algorithms because only the algorithms coefficients were amended. The simulations and experiments illustrate that the optimized algorithms can reduce effectively the additional algorithm errors and increase obviously the algorithms precision. The algorithms have great value to real application.]]></description>

Considering the imaging constraints of EOS, to make replete use of the resource, the label vertex digraph without circuit as the model of imaging scheduling problem was adopted. On the basis of this model,  a multi-objective scheduling method, based on the Strength Pareto Evolutionary Algorithm 2, was presented and also genetic operators to handle the imaging constraints were proposed. This method was tested on three real problems with two objective functions. From the results, it can be said that the proposed method can resolve the EOS scheduling problem efficiently.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Concerning the problem that the existence of secret information of the stego-image on wavelet domain is subject to detection by histogram analysis for wavelet coefficient, and the visual property that human eyes are less sensitive to textured areas of an image, a novel steganography on wavelet domain against statistical analysis based on HVS (human visual system) was proposed. First, an image was divided into blocks of prescribed size, and every block was decomposed into wavelet using IWT (integer wavelet transform) based on lifting scheme. Then, all nonzero wavelet coefficients were classified into two categories according to their sign and parity, and marked by steganographic 0 and 1 respectively. If the identifier of wavelet coefficients was different from secret bit, it would be modified to the opposite one, otherwise unchanged. And more secret information was in turn embedded into 2 or more level wavelet coefficients in textured blocks so that good visual imperceptibility was obtained. Finally, the stego-image was obtained by the inverse wavelet transform. From the experimental results, the proposed method effectively keeps the identity of histogram for wavelet coefficients and maintains a good visual quality of stego-image.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Optimality analysis of linear programming is used extensively in economy and management. The optimal objective value is a complicated piecewise linear function of the right-hand-side vector of the constraints, and its analytical expression is normally hard to obtain. Four metamodels, that is, polynomial regression, radial basis function, Kriging interpolation, and polynomial regression hybridized with Kriging interpolation, are used to rapidly predict the optimal objective function value. Comparative analysis through simulation experiments shows that the last three methods can provide higher accuracy fitting with fewer experimental designs. In particular, polynomial regression method hibridized with Kriging interpolation can not only have a good fitting accuracy but also give a simple approximate expression of the optimal objective function value using a second-order polynomial. The results show that the metamodel method is effective for optimality analysis of linear programming.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The paper proposes a new classification feature: DI(Diversity Index), considering the characteristics of satellite cloud image. The DI feature presents the structure of cloud effectively and it has a good robustness. The DI feature avoids the influence exerted by the variety of cloud positions. This paper proposes the semi-supervised FCM (SSFCM) method in the domain of satellite cloud images classification. The SSFCM method overcomes the blindness brought by the FCM method without considering the domain knowledge. The SSFCM method uses a small number of samples labeled by experts to direct the clustering process through comparing with the labeled samples in terms of similarity. These labeled samples represent the domain knowledge. The experiments demonstrate that the SSFCM method improves the accuracy of cloud classification based on the DI feature.]]></description>

First, the similarity relations among objects with hybrid data are defined. In order to obtain reasonable soft partitions among objects, the optimization model for threshold accounting is presented. Then, based on the upper and lower approximation concept from rough set theory, the covering upper and lower similar partitions among objects are obtained. In succession, through descriptions of the upper and lower similar distribution matrixes found on condition attributes and decision attribute, the two attribute reduction results of different viewpoints can be retrieved intuitively, based on the max-distribution matrixes.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[PN code ranging technique based on DSSS is widely used in satellite navigation, radar, and aerospace TT&C. The phase distortion introduced by RF link and cable multi-path will greatly affect the signal time delay of spread spectrum. The traditional definition of group delay is incapable of describing the holistic phase character of signal bandwidth, thus having difficulty in establishing relationship with the spread spectrum signal delay. To resolve these problems, a new group delay definition has been put forward, based on Taylor series expansion, which uses zero order group delay, linear group delay and parabolic group delay to describe phase distortion. The influence of the different order group delay on PN code ranging was analyzed and simulated. The results show that the parabolic group delay has greatest effect on PN code ranging.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The vehicle-mounted forward-looking ground penetrating imaging radar (VFGPIR) is a feasible facility to detect shallow buried objects, but it faces a high false alarm rate. The combined detection, by using the sequence features, is proposed as the key to solve this problem. Firstly, we use the Fisher's discriminating ratio (FDR) to quantificationally evaluate the discriminating power of the individual feature component extracted from the single or serial images. Since the optimal individual sequence feature cannot satisfy the needs, a multi-features joint detection method based on the decision-level weighting fusion is presented in this paper. Finally, the receiver operating characteristic (ROC) curve is exploited to demonstrate the validity of the proposed method. Experimental results of the data show that the features extracted from the sequence images have better discriminating power, and the suggested method has a better detection performance than that of the optimal individual sequence feature, feature vector, and majority voting fusion rule. The approach is expected to satisfy the requirements of landmine detection in the practical application.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A compact two-dimensional(2-D) finite-difference frequency-domain method is used to analyze propagation characteristics of generalized ridge waveguides for the first time. Only four transverse field components are involved in the final resulting eigenvalue problem, so the required CPU time is reduced considerably as compared to the approaches by which six field components are comprised. Additionally, the feature of finding the phase constant for a given frequency is more pertinent in practical applications. To deal with the generalized ridge waveguides, we divide complex structure into several regular sub-regions, and apply the compact 2-D FDFD method respectively in every sub-region only by setting boundary conditions accordingly. Finally, the calculated numerical results in the current study show good agreement with the published ones in this field.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The fractional Fourier transform (FRFT) is a generalization of the Fourier transform. To the linear frequency modulation (LFM) signal, the FRFT is a good way for signal accumulation. Aiming at the linear frequency modulation characteristic of the anti-radiation missile (ARM) echo signal, an improved method for ARM detection based on FRFT is proposed. The areas of peak search were reduced and the detection efficiency was improved when the FRFT was localized. The simulation experiments show that the reliable detection of ARM signal can be achieved with this method under the Gauss or non-Gauss clutter environment.]]></description>

Thus, the problem of resolving the reflection position is notoriously ill-posed.

In the approach, an efficient model checking system was suggested. The new approach can effectively shorten verification cycle, and give counter example when the system specification is unsatisfiable. All this greatly helped rapid error location. The analysis and experiment results prove the effectiveness of our method.]]></description>

At last, we use these feature regions to construct affine invariants, based on affine geometry invariant property. In order to validate the image invariant's stability and high time efficiency, experiments were performed and the proposed method was analyzed in comparison with the existent methods.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In the test evaluation for small sample size, the prior information is generally fused to obtain the evaluation result with weight calculated by the data consistency check for test information and prior information. However, in small sample case, the consistency between two kinds of samples may be unstable. To improve this situation, the physical equivalency credibility is defined by analyzing different test surroundings. Moreover, the composite equivalency weight of prior sample is decided by fusing physical equivalency credibility and data consistency. A weighted method for considering the credibility of the prior information is proposed for Bayesian estimation algorithm and the weighted estimation of normal inverse-Gamma distribution parameters is provided. The efficiency of the prior sample is analyzed by comparing the posterior variances for different cases, and is further applied to determine whether the prior samples should be fused in the conception that only those prior samples which can reduce the posterior variance should be used. Theoretical analysis and simulation demonstrate that this method is credible.]]></description>

But these schemes are sensitive to the nonlinearity of high power amplifiers (HPA). The nonlinearity of HPA causes inter symbol interference (ISI) and adjacent channel interference (ACI). A scheme for adaptive digital predistortion based on RBF neural network for HPA onboard the satellites was proposed to linearization HPA .

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Focusing on the problem of moving object detecting before tracking in image sequences with complex background, a new salient feature extraction algorithm that fuses the motion characteristics of objects is proposed. The algorithm fuses the gray-level and the detail and motion of the objects to form a robust salient image. The regions with salient multi-features are enhanced and the others are restrained, so moving objects will easily be detected in the salient image. The salience of the objects in the algorithm is derived from the local difference of multi-bottom features of the image, so the algorithm is robust. The experimental results show that the new algorithm is practical and stable, and has the strong anti-jamming capacity. The visual effect of the experiments demonstrates that this method can improve the signal-clutter ratio.]]></description>

The time and frequency domain results show that there is stochastic resonance and a dimensionless frequency sensitive range of 0.2-0.8. Thus the model can help to detect the sinusoidal signal. In addition, the frequency sensitivity coincides with the findings in biology and is beneficial to disclosing the secret in the signal transmission of neuron and neural system.]]></description>

A new lossy compression method for hyperspectral imagery oriented anomaly detection is proposed. In order to keep the performance of anomaly detection, the anomalous vectors detected by the improved RX algorithm are preprocessed. Furthermore, virtual dimensionality algorithm is introduced to estimate the Intrinsic Dimensionality (ID) of original data while Karhunen-Loeve transform is used to provide spectral decorrelation. In addition, based on the virtual dimensionality, a new method for the number of principle component determination is presented. The bit rate of each principle component is distributed by optimal rate allocation strategy for spatial compression by SPIHT algorithm. Experimental results show that the proposed algorithm provides better compression performance, as well as efficient preservation for anomalous pixels.]]></description>

The  distribution is able to accurately model the homogeneous, heterogeneous and extremely heterogeneous regions in a single look or multi-look SAR image. But its applicability is greatly limited by its disadvantages that the parameter estimation is complex and the threshold cannot be acquired easily. In view of these problems, this paper uses the moment estimation and dichotomy method to complete the parameter estimation and the threshold acquirement. In addition, pre-filtering the target candidate regions and iterative calculation are used to increase the efficiency.

Based on sphere target assumption, the current research presented a circuit that can generate second order Gaussian impulse for fuse return signal simulator, using step recovery diode and UWB filter co-design. Parameters of SRD circuit and UWB filter were determined by simulation. According to simulation results, a impulse circuit was fabricated and measured. The measured results coincide with theoretical second order Gaussian signal.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The nonlinear effect of phase performance and the dependency relationship of envelope delay with the change of frequency for a radio frequency module are owed to a good many factors uncertainty, which may cause the waveform of output radio frequency signal to be distorted. Based on the recursive least square adaptive filter, the novel method to eliminate nonlinear effect of radio frequency module was proposed. By regarding the GPS simulating system as an example, the model parameters were estimated precisely by using its self-revising module, software radio technique and digital signal processing technique. Then in order to eliminate the nonlinear phase and variable envelope delay, the synthetic signal in baseband was processed using a digital filter, which was the inverse filter of radio frequency module. The corresponding computation was accomplished utilizing the self-programming emulating package with the help of Matlab. The simulation results indicate that the method proposed in this paper can eliminate the impact on radio frequency signals by the nonlinear effect of phase, and the waveform distortion of output signals can be reduced to less than 0.01 percent.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Current literature on indexing current and future positions of the moving objects lacks the mechanisms on concurrent access. To solve this problem, the current research proposed an efficient moving object index  that supports concurrent access, also called CS<sup>2</sup>B-tree(Concurrent Space-filling curve enabled Cache Sensitive B<sup>+</sup>-tree). CS<sup>2</sup>B-tree combines the characteristics of the B<sup>x</sup>-tree and CSB<sup>+</sup>-tree, thus it can support querying the predicted future positions of the moving objects and is cache sensitive. Focus was put on studying a concurrent access mechanism to CS<sup>2</sup>B-tree which resulted in a two-level lock mechanism and particularly a lock memo structure was designed. Based on the concurrent access mechanism, a CS<sup>2</sup>B-tree concurrent location  update algorithm and a concurrent predicted range query algorithm were proposed respectively. Experimental results show that, compared with B<sup>x</sup>-tree, the throughput of the CS<sup>2</sup>B-tree improves by 15.1%, and the response time decreases  by 14.9%.]]></description>

Aiming at this problem, a new inversion method based on the BP neural network was proposed. The new method directly fits the nonlinear mapping relationship between the complex polarimetric correction coefficients and the vegetation height, so it can reduce the error caused by the error in the estimation of the ground interferometric phase, and that caused by the scattering model error. The new method has better performance than the three-stage vegetation height inversion method, and the simulated results validate the superiority of this new method.]]></description>

It can find applications mainly in binary image restoration, image quantization and image segmentation. Different part of an image varies differently, thus it needs varied number of quantized levels. Different image histogram also corresponds to different quantized levels. We made improvements to the quantum TV algorithm according to the above statements.

The influence of the moving error and the field's noise, which may appear in practical application, has been discussed by simulation method combining theoretical derivation. Research shows that it can achieve the best effect with three times of scanning only. In the presence of system error or random error, the quality of processed image will decline along with the increase of scanning times. So the imaging result and velocity are not contradictory in this technology. Furthermore, the quality requirement to stripe field is not strict. Generally, the effect of processed image using noisy stripe field whoes SNR is from 15dB to 20dB is very close to the ideal effect.]]></description>

Only when the noise FRT spectrum is well estimated, the required image FRT spectrum can be well separated and return to the space domain with the inverse ransformation. As a result, we find that the method simplifies the process of restoration and the blind restoration will be obtained when we know nothing about the degradation process affected by various factors.]]></description>

Moreover, the calculation expression about lower bound of the error probability solely depends on the Hamming weight enumerator function of the code and the crossover probability of the channel. The simulation results applying to various LDPC codes show that the new lower bound outperforms those generic lower bounds and the sphere packing bound.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A multi-satellite cooperative planning problem model was given considering the characteristics of the task requests and satellite 
constraints. Then the original performance function of each satellite agent was modified by introducing both the constraint punishing operator and the multi-satellite joint punishing operator. Next, a multi-satellite reinforcement learning algorithm (MUSARLA) was proposed to derive the coordinated task allocation strategy. Furthermore, the interaction among multiple satellites was designed based on blackboard architecture to reduce the communication cost while learning. Finally, simulated experiments are carried out which verified the effectiveness of the proposed algorithm.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[With terrorism aggravating, anti-terrorism has been a main task for national military security departments around the world. The current study utilized categorical data visualization, Parallel Sets, to analyze the relations among the multi-categories in Global Terrorism Database, aimed to uncover the implicit information within the data set. To alleviate the deficiency of excessive edge crossing brought by random layout of categorical values, the research proposed a heuristic layout algorithm based on average heuristic with cardinality reduction, which optimized the layout order of categories and the visual clutter is eased so that the cardinality reduction strategies can reduce the numbers of categories involved in computation. The experimental results demonstrate that the improved parallel sets can clearly express the association among
 the multi-categories in Global Terrorism Database, thereby assist users in analyzing the information of various terrorist organizations, such as the behavior characteristics. Furthermore, the average-based heuristic with cardinality reduction is simple and highly efficient, which is suitable for large data sets with many categorical attributes.]]></description>

Based on the double sparse image representation model proposed by Rubinstein, the zero-tree structure of wavelet coefficients was introduced, and the new dictionary atoms were constructed by linear combination of wavelet bases in all high-frequency bands of same orientation across different scales. The linear combination coefficients were learned via K-SVD. The image decomposition and reconstruction algorithm was proposed based on the learned dictionary. The M-term approximation and compression of remote sensing images both proved the better effects of the proposed structured dictionary than the existing dictionaries.]]></description>

A novel method, therefore, is presented to detect weak signals from the probe, which are directly sent to digital signal processing system after signal conditioning and sampling. In this method, the characteristics of the weak signals are extracted by wavelet transform and the amplitudes determined by the correlation method. The simulation results indicate that the probe’s output signals with SNR=-15dB can even be detected by the hybrid method mentioned above.]]></description>

A mixed-mode simulation method is proposed for computing SER in combinational logic, which is aimed at solving the slow HSPICE simulation speed and the low precise of traditional methods in treating re-convergence. A Mixed-Mode Analysis Tool for Combinational Logic based on this method was implemented. Re-convergence logic gates were simulated with HSPICE; a fast pulse propagate algorithm was used to simulate others. The simulation results illustrate that the proposed method gains a close precision to HSPICE with a faster speed. Compared with the prevalent SER analysis method, it is found that our proposed method can factually reflect the SER in combinational circuits where there are many re-convergence logic gates.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Aimed at the Low-angle Height Finding problem under multi-path environment, a novel low angle height finding algorithm at sub-array level is proposed. First, the whole array was divided into three equal sub-arrays. Then, the orthogonal vector of covariance matrix at sub-array level was calculated accurately, not by Eigen Decomposition. Next, the angle spectrum was presented, whose peak just accords with the DOA of target. Finally, the complex reflection coefficient was estimated after the estimated DOA. How this algorithm relies on the SNR, the target’s elevation and complex reflection coefficient has been explained by simulations. Its efficiency was verified by outdoor data obtained by VHF band radar. The elevation angle error is 1.19 percent of beam width of array. This algorithm is independent on the unknown complex reflection coefficient, and the computation is lowered greatly. It can be applied in ship borne radar and VHF band 3-coordinate radar.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The routing and channel assignment (RCA) can affect the performance of wireless mesh networks (WMN) largely. In order to solve the RCA problem of WMN, a scheme called CRAG (Channel and Routing Assignment based on Game) for WMN is proposed and studied. CRAG is a kind of coordination game which models each node of the network as a player. The players strategy is the routing and channel assignment scheme related to the node. The payoff function is the successful transmission traffic given a traffic demand matrix. Player coordinately optimizes the payoff function to maximize the network throughput. Simulation results based on NS3 show that CRAG performs much better than other state-of-the-art schemes in terms of convergence, delay, loss rate and throughput. It proves that coordination game can be used to solve the RCA of WMN and improve the performance of network effectively. ]]></description>

For every particle, the algorithm exploits likelihood between latest measurements, and the particle chooses one measurement of the set of measurement to obtain importance distribution by update particle, and draws samples of survive particle from the importance distribution. The presented algorithm reduced degeneration of particle efficiently. In simulation scenario of 3 targets tracking, the optimal sub-pattern assignment metric of particle probability hypothesis density filter, which adopted the presented survive particle importance sample method, decreases about 70Km when targets model used in target tracking method is different from actual targets model. The proposed method enhances the robustness of multitarget tracking of particle probability hypothesis density filter remarkably.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The resolution of space object images observed by ground-based telescope is greatly limited due to the influence of atmospheric turbulence. An improved blind deconvolution method is presented to enhance the performance of turbulence degraded images restoration. Firstly, a mixed noise model based blind deconvolution cost function was deduced under Gaussian and Poisson noise contamination of measurement. Then, point spread function (PSF) was described by wavefront phase aberrations in the pupil plane according to Fourier Optics theory. In this way, the estimation of PSF was generated from the wavefront phase parameterization instead of pixel domain value. Finally, the cost function was converted from constrained optimization problem to non-constrained optimization problem by means of parameterization of object image and PSF. Experimental results show that the proposed method can recover high quality image from turbulence degraded images effectively.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to reduce the bad effect in the outdoor visibility system in foggy days and achieve the real-time dehazing effect, a fast and effective method, which is based on Bayer pattern image and dark channel prior, was developed to remove the haze from single image. The color image processing pipeline was improved through this method. Bayer pattern image is the raw data captured by digital camera and costs low memory. According to the characteristics of Bayer pattern image, the original dark channel prior algorithm was optimized and improved. The atmospheric light was estimated based on the quad-tree subdivision. In the optimization process of the transmission map, the coarser estimation was refined using the Guided Filter, which was modified with the property of Bayer pattern image. Finally, the RGB image, which is displayed by the device, was recovered from the haze removal Bayer image using the demosaic algorithm. The experimental results show our new single image haze removal method improves the image quality by reducing the haze effect, and enhances the calculation speed.]]></description>

The extractor operating at 3π/2 mode not π-like mode improves the group velocity of wave, which is favorable for RF extraction. The loaded quality factor of the buncher is increased by introducing a prior reflector, which can obviously reduce the starting time of microwave. The device is designed and optimized by a PIC (particle in cell) code. With the voltage 530 kV，the current 12.8 kA and the guiding magnetic field 0.7 T, the output power is 2.41GW at the main frequency 7.76GHz, and the efficiency of beam-to-microwave power conversion is about 35.5%.]]></description>

Mutual coherence function of signals penetrating through the ionosphere was deduced. Electron density in the ionosphere was modeled by Rino's power density function. Patterns were studied that how spaceborne P band SAR image performances varies with parameters of ionospheric irregularities. The study shows that irregularities in ionospheric will defocus the image, causing considerable gain loss of the imaging. Increases in irregularity strength parameter CkL, outer scale Lo, and index of the power density function will further degrade the image. The study is validated by numerical simulation based on phase screen technique.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Multi-view point cloud scenes mosaic is an effective method to solve the incomplete object data problem while self-occlusion and occlusion happened in laser 3D imaging process. The mosaic method directly affects the object detection and recognition. In this research, a particle swarm optimization(PSO)based mosaic algorithm is proposed. The projective distribution entropy to construct the scene's coordinate was used, and the transformation between point cloud scenes by the coordinates was estimated. Based on this, the objective function for the mosaic was constructed, and the PSO for optimization was used. In the optimization process, the minimum miscarriage of justice method was used for searching the correspondence. In this way, the optimal transformation was found, and the fine mosaic was realized. Experimental results demonstrate the effectiveness and feasibility of the proposed algorithm.]]></description>

The property functions of two status variables were designed according to the method of fuzzy reasoning. The study constructed the inference rules of the system after acoustic energy attenuation model and the variety of magnetic field model were built, and the rationality of constructed rules was checked. The comparison between theoretical analysis and simulation result show that intuitionistic fuzzy reasoning can classify targets uncomplicatedly and effectively. Because of its less calculation, the method can apply to WSN node, in which the calculation capacity is weak.]]></description>

In light of this, the properties of a SIW longitudinal slot with a dielectric cover were extensively investigated using equivalent relationship between SIW and conventional waveguide together with Method of Moment, as a first step to the design of a SIW slot array and its integrated radome. The accuracy and efficiency of our method was assessed against Ansoft HFSS. The computational time was significantly reduced by a one-order magnitude with acceptable computational accuracy. Finally, effects of the dielectric-cover were extensively investigated through three typical cover configurations and some instructional conclusions were drawn, which finds further application for the optimization design of the dielectric covers to improve the antenna performances.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Spectrum sensing technique for wideband analog signals has been applied widely in cognitive radio. Based on the idea of time-division, this study was conducted with the following steps. Firstly, sampling time was divided into time slices which have fixed length. Secondly, the signal was multiplied by a bank of periodic waveforms which are modulated by pseudorandom number generators, and the product is low-pass filtered and sampled at sub-Nyquist rate. Finally, the samples were used to evaluate frequency support. Compared with the multi-channel structure, the single-channel structure proposed here is much simpler and has the ability to spectrum sensing with low-rate samples. Numerical simulations show that this algorithm can effectively use samples sampling at sub-Nyquist rate to finish the task of spectrum sensing in scenarios that the spectral support is unknown in advance.]]></description>

The characteristics of Lagueree function and its time derivative were studied, and the time derivative inner matrix was derived, which was applied in Fisher matrix, then the CRLB can be calculated fast and accurately. The simulation on hybrid exponential model polluted by Gaussian white noise testified the well coherence between the variance of ToF and the theoretic CRLB obtained with Laguerre model.

The traditional navigation and positioning error propagation model cannot be applied to analyze the error in this emergency assisted positioning mode. To solve this problem, this research focused on the basis of several emergency auxiliary positioning principles, such as three satellites combined with the elevation, three satellites combined with clock bias, two satellites combined with elevation and clock bias, and provided a new error propagation analysis model of emergency auxiliary positioning, verifying the correctness of the model by simulation example. Finally, through the positioning accuracy analysis, it concluded that the present method can quantify the optimal magnitude relations between pseudorange measurements and the accuracy of the auxiliary information with minimum cost to improve positioning accuracy, which can guide the choice of external auxiliary devices for navigation receiver.]]></description>

This research proposes a kind of Reconfigurable Computing Application 
Framework BSRRCS-RCAF for the specific application of Broadband Signal Reconnaissance, which extracts and collects the computing and function modules as the form of library of configurable files. When the system of Broadband Signal Reconnaissance needs to be modified or reconstructed, the user, who is also the designer of the system, only needs to schedule the components from the library dynamically, or complement the special 
functions of the system, then the framework of the system will be reused conveniently. Based on BSRRCS RCAF, it is easily and quickly to realize the system with multi-functions.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Aiming at the face recognition problem, a new supervised dimensionality reduction algorithm is presented. On the basis of sparse representation theory, the proposed algorithm uses the within-class sparse construction to construct graph. This scheme can avoid the difficulty of parameter selection in traditional graph construction methods, and characterize the within-class information well. Furthermore, the multi-class nonparametric discriminant scatter is applied to characterize the between-class information, which will be more discriminative than parametric discriminant scatter in dealing with complex-distributed data. By maximizing the nonparametric between-class scatter and preserving the within-class sparse reconstructive relationship, the proposed algorithm can seek for the optimal projection matrix. Experimental results on ORL and Extended Yale B dataset show that the proposed method can achieve good recognition effect. ]]></description>

Aiming at the problem that currently the national measurement accuracy of inter-satellite time-tag offset cannot satisfy the demand for time-tag error correction, a novel correction method based on the combination of two optimal frequencies is proposed, and the quantity relation of the optimal frequencies is deduced. Research on the realization for combination of two optimal frequencies, which shows that it is unrealizable utilizing the existing KBR system, was performed. Consequently, a new KBR system adopting an advanced frequency flow was designed and realized. The experimental results demonstrate that the proposed method and the advanced KBR system effectively reduce the requirement for measurement accuracy of inter-satellite time-tag offset. ]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Solving the spatial optimization problems can be a complex and difficult task, since it has to handle some high-dimension, non-linear, complicated relationships. Many efforts have been made with regard to this specific issue, and the strong ability of artificial immune system algorithms has been proven in previous studies. In this study, a novel framework used for spatial optimization based on clonal selection algorithms, which are the most popular immune algorithms in geoscience, is proposed. Then, the spatial optimization platform was designed based on the architecture of “plugins – platform”, and some key technologies about the developing of immune operator plugins and spatial optimization application plugins were described. Based on the standard APIs provided by this platform, researchers can develop their own 
problem-specific application plugins to solve the practical problems or to implement some advanced immune operators into the platform to improve the performance of the algorithm. Finally, the functionality, reusability and extensibility of platform were tested by using the Traveling Salesman Problem as a benchmark testing. Experiments show that, the platform is capable of solving various optimization problems, and it is expected to bridging the gap between the immune algorithm researchers, geographers and decision makers.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Grid-to-grid routing algorithms for distributed hydrological modeling require large amount of computations which cannot be provided by sequential computation techniques. Parallel programming technology is necessary for large-scale and long-period simulations using grid-to-grid routing algorithms. There is currently little research on the parallelization of implicit finite difference based routing algorithms. A parallel implicit finite difference based grid-to-grid routing algorithm was presented, based on grids layering. In this algorithm, grids in the watershed were divided into different layers according to flow direction. The calculations of grids in a downstream layer cannot be performed until its upstream layers’ calculations were completed. The calculations of grids in the same layer are independent of each other, thus can be performed in parallel. So the parallelization strategy is to assign the calculation tasks of grids in the same layer to different CPU-cores to perform parallel computing. The algorithm was implemented by using the C++ programing language and the Open Multi-processing (OpenMP) Application Programming Interface (API) and was tested in the Qingshuihe watershed of Hebei Province under different amount of input data. The result shows that this parallel algorithm had good speedup and parallel efficiency. In addition, the case study showed that the parallel efficiencies were higher for simulations with large datasets than with small datasets and the up-down layering method had better performances than the down-up layering method.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Data granularity is one of the most important issues of parallel computing based on large volume of spatial data. After a comparison with the different types of terrain analysis algorithms, a Geo-Data Granularity Model (GDGM in short) was proposed, which can be used for the quantitative description of data partition granularity in parallel computing process of massive spatial data. In this algorithm, according to the parallel evaluation method, the parallel data granularity was adaptively adjusted and finally an optimized data grain was obtained. The execution time of each parallel computing was recorded for the comparison of computing efficiency values from different data granularities. Furthermore, by means of the comparison, a dynamic algorithm was designed for the dynamic scheduling of different data granularity so that the optimal performance of specific algorithm was achieved. The preliminary experiments show that the algorithm has much better efficiency and portability than the traditional ones so far.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Spatial join aggregate (SJA) is a commonly used but time-consuming operation in spatial database. Especially when faced with the deluge of spatial data，SJA is difficult to be implemented on a single machine. Consequentially, how to design efficient distributed SJA algorithms is receiving more and more attention. Constrained by the sequential scan operation assumption, Map-Reduce is usually used to accelerate the non- indexed spatial join query, but none of the previous work can process SJA with both Map-Reduce and R-tree spatial index. Thus, a novel algorithm, R-tree based Spatial Join Aggregate with Map-Reduce (RSJA-MR) was proposed, which is able to return results more efficiently. A distributed R-tree index structure was presented to index the large-scale spatial data. RSJA-MR first made use of distributed R-tree to generate the tasks. Those tasks met independent parallel computation and could easily be expressed in Map-Reduce. An index cache mechanism was provided to support the concurrent access of R-tree index. The experiment results show that, compared with the non-indexed SJA , the time performance of RSJA-MR is improved at least by 8% for spatial intersection join aggregate and by 35% for spatial containment join aggregate.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In the development of GMI magnetic sensor, weak magnetic signals are always submerged in the circuit intrinsic noise. Since traditional peak detecting method is impossible to detect GMI sensor’s output when its SNR is lower than 0dB，a new method is presented to detect the GMI probe’s weak signals（SNR<0dB）. The LMS algorithm was applied firstly to extract the characteristic parameters of the weak signals, and then the cross-correlation function between the characteristic parameters and the idea ones was calculated. Finally the maximal correlation values were regarded as weak signals to be detected by means of calibration. The simulating results indicate that this method can not only detect but also measure the magnetic field by the corresponding relationship of magnetic field intensity and the maximal correlation values, even the SNR of GMI magnetic sensor’s output is  10dB.]]></description>

Therefore, a finger-vein structure description method based on B-spline was proposed. The new method obtained the coordinate set of all target points on every finger-vein branch by using line scanning operation on thinned finger-vein images. A B-spline function was used to fit the curves of finger-vein branches. The control-point coordinates of every B-spline curve were gained, and they were used to describe the line-structures of finger-vein. Experiments show that the new method can availably describe line-structures of finger-vein with little description error and small storage space requirements.

The operating principle of this SPA was analyzed and the equivalent circuit models were established under different working states including critical commutating state, natural commutating state and compulsive commutating state. The equivalent circuit models were emulated in OrCAD when the SPA worked in critical commutating state. For the acquisition of power amplifier and load current value about SPA in natural and compulsive commutating state, the nonlinear mathematical models were established in the base of equivalent circuit models, then they were solved by fourth-order Runge-Kutta method under the platform of Matlab and VC++. The methods mentioned can calculate the voltage and current at any time any point of the SPA; it can reflect the working state of circuit objectively and factually; the research may be of certain reference for engineering application.]]></description>

A test showed that the Bragg mode is realized at 9.7GHz and the quality value is greater than 200,000. The Bragg mode is being used as band pass filter to build X band oscillator, which includes low noise amplify, filter and mechanical phase shifter. The oscillator realized stabilization by choosing proper insert loss and adjusting phase shifter. A secibd test showed that the oscillator has low phase noise output and is vulnerable to environment temperature.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[On the basis of the giant magnetoimpedance (GMI) effect found in the amorphous wire, and with the utilization of the CoFeBSi amorphous wire as the sensing material, a novel differential-type high sensitively sensor adopting the technology of orthogonal lock-in amplifier was designed. Firstly, the concept of the GMI effect and the magnetic sensing head based on the double-sensing-elements and differential-type structure, were briefly instructed. Secondly, the principle of the conditioning circuit of the sensor based on orthogonal lock-in amplifier was analyzed in detail. Thirdly, based on the impedance magnitude and phase characteristics of the amorphous wire, an approximate algorithm was put forward to calculate the envelope of the output of the orthogonal lock-in amplifier for simplifying the arithmetic circuit. Experiment results show that the sensitivity of the sensor can achieve about 748mV/Oe with the full measurement range of -2.0Oe ～ +2.0Oe, and the linearity error is about 0.98%FS, while the average noise power spectral density is about 0.8nT/Hz<sup>1/2</sup>.]]></description>

According to the maximum a posteriori (MAP) and the minimum mean of square error (MMSE) rules, two estimators were derived combining the received training signal with the probability distribution function (PDF) knowledge that cascade channel comprises two independent Rayleigh channels. Due to the intractability of exact Bayesian Cramer-Rao Bound (CRB), alternatively, the approximated Bayesian one was obtained based on the principle of maximum entropy to compare with the CRB of MLE. The numeral simulation demonstrates that the new MAP estimator can bring about significantly improved performance, especially in the low signal-to-noise ratio regime.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to ship model the Shaft-ELFE in shallow sea, the basic simulation unit-time-harmonic horizontal electric dipole was taken for example, the Hertz vector potential was solved based on the uniqueness principle combined with boundary conditions. The electromagnetic field in shallow seawater was derived from the relational expression between Hertz vector potential and  electromagnetic field. The electromagnetic field distribution of DC dipole in three media was solved. The simulated results show that the horizontal electric cell can be used to compute the harmonic cell at sufficiently low frequencies between 1Hz and 7Hz. The conclusion was further confirmed in laboratory, utilizing the horizontal electric cell and the horizontal harmonic electric cell source in man made seawater. Finally, the shallow marine environment and horizontal time-harmonic electric dipole were simulated in the laboratory, the electric field distributions of time-harmonic electric dipole and DC dipole were compared. The results show that the time-harmonic electric dipole electric field distribution was consistent with the theoretical calculation, which proved that the derivation and analytical expression are correct; the horizontal time-harmonic current model can be replaced by horizontal DC dipole when the envelop of shaft-ELFE is simulated, and has a higher accuracy and practicability.]]></description>

However, Kriging interpolation would inevitably encounter the performance bottleneck when the output grid or input samples increase. Implemented with OpenCL and OpenMP, the ordinary Kriging interpolation was accelerated on heterogeneous platforms: GPU and CPU. By considering the performance difference of CPU and GPU on the densities of samples, a new load balancing method of LBCPDD (Load Balancing based on Computation Performance and Data Distribution) was proposed, in which not only hardware performance but also data distribution characteristics were taken into account. Experiment results show that LBCPDD method can effectively enhance the speed of ordinary Kriging, save memory space and improve the efficiency of memory access.]]></description>

Respectively through the actual array method, the traditional LP virtual array method and the improved LP virtual array method, the beam performance of assumed array was simulated and the data from lake trial was dealt with to form the imaging of echo highlights. Result shows that the improved LP method is more effective than the traditional LP method in suppressing the side-lobe of wave beams, and further improves the angle resolution and array gain. And when the improved LP method is applied to practical engineering for bottom target detection under specific experimental background, the directional resolution accuracy can be increased by 75%.]]></description>

Using the sensors attached into the stretchy fabric (For example, belt and wristband), the system can receive physiological signals such as pulse wave and respiratory wave. A condition recognition algorithm was proposed to distinguish conditions such as lying, standing, sitting, walking, running and sleeping by analyzing the geometric features of the respiratory signals received from piezoelectric film sensors. Taking advantage of the relationships between pulse wave translation time and blood pressure to calculate diastolic blood pressure and systolic blood pressure of user, the pressure-free blood pressure measurement was achieved. The nodes communicated with each other through Bluetooth. The data were displayed on the wearable display devices and mobile devices. The system realized continuous and dynamic monitoring of physiological signals, such as the pulse wave, the respiratory wave, the blood pressure.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A dual-band circularly polarized patch array using a sequential-phase feeding network was presented. The array includes four metal patches and a metal square ring. Each rectangle patch was cut in diagonal corners, and was excited by feeding lines on the edge. The feeding lines are microstrip which are connected to the middle metal square ring. In addition, four patches are rotated arrangement. The middle mental square ring is not only a feeding network which provides increasing phase for circularly polarization, but also a radiator which enhances the performance of the array. With this feeding way, the patch array just has single-layer substrate and it is compact. In addition, it radiates circularly polarized patterns in two working bands. Through fabrication, test and measurement, the  -10 dB impedance bandwidth of the patch array is 5.17 GHz～5.59 GHz and 5.99 GHz～6.27 GHz. The measured 3 dB AR bandwidth is 5.19 GHz～5.49 GHz and 6.1 GHz～6.18 GHz. ]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In 3D-IC (three dimensional-integrated circuit) technology based 3D SRAM(three-dimensional static random access memory), a large number of TSVs (through silicon vias) have been implemented in circuits. The manufacturing process of TSV is not mature，which makes TSVs  more prone to open defects and brings new challenges to the 3D SRAM test. The existing method of TSV test can find out where the faults are, but it needs extra specific circuit to implement, which increases both the area overhead and its design complexity. In consideration of what was discussed above, a new idea to detect the open defects of TSV based on a test algorithm was proposed. It proved to be an effective method to detect the open defects of TSV in 3D SRAM using BIST(built-in self test) without any extra overhead. Results show that the proposed method has no functional problem with the algorithm and it can realize the purpose of TSV open fault detection.]]></description>

The ANF was constructed by a series of the first order IIR notch filters, and the frequency parameters of all filters were updated with adaptive algorithm to detect jamming and to suppress it in real time. Simulation results show that the present method is able to suppress the jamming effectively and quickly, and the capability of signal acquisition is enhanced under condition of jamming.

Therefore, a technique based on antenna-array direction change was presented. The carrier phase double differences were estimated in different antenna-array directions, and then the carrier phase double differences were used to discriminate the spoofing signals.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to analyze the structure stress and the current density distribution on the pulsed reactor in the course of working, the test on the stress was designed. The hoop stress on both the edge and the center of copper belt was obtained by the resistance transducer. The stress result was validated by calculating the thick wall cylinder model with the inflation pressure. To calibrate the stress value, the copper belt coil with a ballonet inside was designed. The half-bridge circuit, electrical grounding of the bridge cases and shielding wires were designed and put in practice to reduce the pulsed electromagnetic interference. The disturbance generated by the parasitic resistance and the stray capacitance was reduced by electrical grounding of the bridge cases. The experiment results show that the hoop strain is larger than the axial strain, the strain on the edge is larger than the strain in the center. Reinforcement should be applied on the edge of the copper belt. And it can be speculated that the current density on the edge is about 1.2 times near the center.]]></description>

Through a sliding time window strategy, a variable selection invoking threshold and a model re-training mechanism, the online characteristic of the model was realized. 1～3 day ahead prediction experiments were done on the basis of the electron flux data, solar wind parameters and geomagnetic parameters in 2000, and the analysis results show that the proposed online PSO-LSSVM model works well and has practicable value for prediction.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[For the problem of uneven distribution of gas hydrate synthesized in porous media, a new method for obtaining hydrate samples in porous media by microwave heating was proposed and a microwave heating apparatus was designed for this method. Based on the electromagnetic theory and the influencing factors of microwave heating uniformity, the adjustable multi-feeding microwave heating system was created. Numerical simulation and relevant heating test were made to analyze the effects of relative positions of the waveguides and specimen on apparatus heating uniformity, by which the feasibility of the apparatus to prepare gas hydrate synthesis was discussed. The results show that the heating uniformity is greatly affected by the variation of distance between the waveguides and specimen and it gets better with distance significantly. The consequence of numerical simulation is consistent with the result of experiment. The heating uniformity of the apparatus is less affected by heating time and the apparatus can meet the requirement of hydrates synthesis in uniformity，and its design may provide certain reference significance for the design of testing devices with some requirements in heating uniformity.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to accurately estimate the tropospheric slant delay of the two-way troposphere time transfer system, the Hopfield zenith delay model and the CFA2.2 mapping function model which can estimate the tropospheric slant delay of satellite signals were analyzed and modified, and was accepted by the accurate estimation of slant delay caused by tropospheric scatter. The meteorologic data of three observation stations from 35°N to 37°N in 2010—2012 were selected to verify that the precision range of Hopfield model was less than 35 mm. Then, in order to calculate the tropospheric delay under different angle of incidence through modified model, three observation stations were distinguished by different baseline distance and the meteorologic data of those stations in 2012 were used. The day of year and the incident angle under maximum slant delay were also obtained. Results suggest that the max delay is 21.82 m to 35.45 m in a single way time transfer. In two-way time transfer, when the delay is counteracted by 90% or 95%, the time delay is 7.3 ns～11.7 ns or 3.6 ns～5.9 ns. ]]></description>

The embryonics array’s functional differentiation and self repairing were achieved through the gene cyclic and non-cyclic shift in the cell and between cells, and the genes stored in memory were updated during the self repairing process. In this memory structure, the gene backups were set according to actual demand of system reliability and hardware cost, which were independent from the number of idle resources in embryonics array. Theoretical analysis and simulation results show that the new genome memory structure can not only achieve  embryonics array’s functional differentiation and self-repair, but also can ensure system reliability and reduce hardware cost, and it has a high practical engineering value.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The atmospheric PWV (precipitable water vapor) was derived from GPS observations of 5 stations over Hong Kong during four years from 2013 to 2016 and the accuracy of PWV(GPS) was assessed with PWV(ECMWF). Based on harmonic analysis, the PWV(GPS) was then compared with rainfall. Taking PWV(ECMWF) monthly means as reference, results show that the RMS(root mean square) of PWV(GPS) monthly means is between 1.02 mm and 3.07 mm and the bias is between -2.14 mm and 2.52 mm. Both PWV and rainfall have similar periodic characteristics. The peaks of PWV occur in July with amplitudes varying between 14.65mm and 16.79mm. And the peaks of rainfall also occur in July and the amplitudes are between 147.64 mm and 211.01 mm. The annual increase rate of PWV is positive at each GPS station, which indicates that the PWV over Hong Kong has an increasing trend during the past 4 years. While the annual increase rate of the actual rainfall is negative except in HKOH station, which means a decreasing trend during the 4 years.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Aiming at the problem that fixed measurement environments cannot establish a fixed base station and thus cannot carry out precise positioning, a differential positioning algorithm for mobile base station based on BeiDou navigation system was proposed, which means achieving high-precise differential positioning while the base station and the rover both moving. Based on the carrier phase measurement, under the condition of dynamic short baseline, the datum were inter-station and inter-satellite double-difference processed, eliminating receiver clock error and other common errors. Based on the linear combination of multifrequency measurement, the observation of the super-wide lane, the wide lane, the middle lane and the narrow lane was obtained, the window-moving average filter was carried out and the ambiguities were fixed by the stepwise ambiguity determination method, that is, along the order from the super-wide lane to the narrow lane to solve the ambiguity. In order to verify the effectiveness of the algorithm, a verification experiment of the external geometric parameter detector based on the BeiDou navigation system was designed to realize the static relative positioning accuracy of millimeter and the RTK relative positioning accuracy of centimeter.]]></description>

During past years, analysis of interferences effects on effective C/N<sub>0</sub> have been put forward. However, effective C/N<sub>0</sub> limits analysis hasn’t been presented. Thus, effective C/N<sub>0</sub> limits were analyzed. The theory model of effective C/N<sub>0</sub> and BER (bit error ratio) were derived in the presence of CWI(continuous wave interference), and results show that effective C/N<sub>0</sub> fails to evaluate data demodulation performance under specific condition. Then, the mechanism of effective C//N<sub>0</sub> malfunction was elaborated and the application condition of effective C//N<sub>0</sub> was presented. Finally, theory analysis is verified by simulations.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The analytical model for the output relations of anti-aliasing filtering, sampling, quantization and de-spreading was established. The formulation of de-spreading output SNR (signal to noise ratio) under the influence of three factors was deduced. Analysis and simulation results show that the total SNR loss can be separated to the product of quantization, filtering and sampling loss when the quantization length up to 4 bit; besides, the optimized clipping level coefficient is only related to quantization length. When the quantization length is less than 4 bit, the total SNR loss approximates to the product of the quantization and sampling plus filtering loss. In the condition of the quantization length up to 4 bit, the filter bandwidth up to 5 times of PN (pseudo-random) code rate, the sample rate up to 4 times of PN code rate, increasing the parameters mentioned above cause the SNR loss less than 0.05 dB, thus the despreading performance cannot be increased obviously. Results can be used to optimize the design of the front-end of lowcost global navigation satellite system receiver.]]></description>

The methods of coordinate setting, focusing on source and compensation about ΔZ on flip chip integrated circuit were proposed and employed. Pulsed laser tests were carried on static random access memory, register file, RapidIO and Dice flip-flop. The results indicate that SRAM is the most sensitive area and the results on these modules are consistent with the corresponding results under heavy-ion experiment. Therefore, the pulse laser is suitable for single-event effect researches on large-scale integrated circuit designed with nanometer technology. ]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In dual-antenna interferometric synthetic aperture radar system, the reference phase was usually estimated by joint calibration with transferring corresponding points for the scene without ground control points, which is too time-consuming. To solve the problem, the factors influencing the reference phase were analyzed. The analytic formula was given, and simulation was done according to the system parameters. The height error caused by reference phase was analyzed. According to the analysis results, the high precision realtime reference phase estimating algorithm was presented, combined with the extern coarse precision elevation, the filtered interferometric phase and coherence. The detailed flow of the algorithm was given. The processing results of the real data from airborne dual-antenna interferometric synthetic aperture radar system validate that a 2 m relative elevation precision can be achieved with the system in the paper by the algorithm presented, and the estimated speed can reach more than 20 times faster when processing the data of 4096×6560pixel.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[With the ionospheric electron density profiles derived from the COSMIC radio occultation mission during 2010 to 2014, the qualities of these profiles were checked comprehensively using four quality control parameters which consider only the profile′s own characteristics. The spatial and temporal distributions of the qualities of the profiles were analyzed accordingly. It is found that the qualities of the profiles are the highest over the high-latitude regions, followed by the low-latitude regions and the lowest over the mid-latitude regions. This may be due to the existence of the equatorial anomaly of the electron density distribution near the magnetic equator. The seasonal variation of the qualities of the profiles is distinct, which shows a significantly higher rejection ratio in winter and spring than in summer and autumn over both of the two hemispheres. In addition, the rejection ratio of the profiles is significantly lower in daytime than in nighttime, and it has great changes occurring at twilight demarcations. The peak electron densities and the corresponding peak heights derived from the qualified profiles are significantly higher over magnetic equator than over other regions, which shows a “double hump” phenomenon.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Once clutter training samples mix with interfering targets, the clutter suppression performance by space-time adaptive processing will decline. In order to solve the problem, a robust training samples detection method based on target knowledge and partly sparse recovery was proposed. Firstly, the object region in unit to be detected was locked. Then the sparse complete base was obtained by covering the whole angleDoppler plane. After that, the corresponding object region in sparse complete base by transformation matrix was hollowed out to obtain the super resolution clutter space-time spectrum, which helps to estimate the clutter covariance matrix. Finally, the method was combined with the generalized inner product method to realize non-homogeneous training sample detection. Compared with GIP (generalized inner product) method, the proposed method can detect interfering targets in different intensity. Simulation analysis demonstrates that the test statistics of the proposed method have excellent discrimination validity, and can drastically eliminate interfering targets, thus improving the target detection performance of STAP (space-time adaptive processing).]]></description>

The optimization problem in which the prior knowledge of the distribution characteristics of target impulse response and clutter impulse response is not accurate was modeled as a maximum minimization problem. During the optimizations, the joint design problem was divided into two steps: the optimization problem of receiver filter weights when the waveform was fixed was modeled as the generalized Rayleigh quotient model, and the corresponding weight vector of the receiver filter was obtained; the waveform optimization problem of fixed weight was solved by using positive semi-definite relaxation technique to obtain the corresponding waveform matrix, and the constant modulus waveform was obtained by Gauss random method according to the waveform matrix obtained. The convergence of the proposed algorithm was proved, and the simulation results show the effectiveness of the proposed algorithm. ]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A de-noising and recognition method based on HHT (HilbertHuang transform) was proposed to solve the problem that the traditional methods cannot effectively identify the pulse eddy current signals produced by small defects with different sizes. Firstly, the pulse eddy current signal was decomposed by EEMD (ensemble empirical mode decomposition), and the IMFs (intrinsic mode functions) of much noise were selected according to normalized autocorrelation function and its variance. Secondly, the selected IMFs of much noise were removed by the wavelet threshold denoising, and then the noiseless signal was reconstructed by adding to the nonprocessed IMFs. Then, the HMS (Hilbert marginal spectrum) was obtained by using HHT. Finally, according to the difference of HMS, the surface and subsurface defects with different sizes were identified. Experimental results show the effectiveness of the proposed method: the noise of pulsed eddy current signal is eliminated by noise elimination through EEMD, and the method based on HHT can effectively identify cracks of different sizes.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The stress image method and the perfect matching layer method were used to deal with the boundary problem of shallow water ship seismic wave field simulation. The algorithm fully considers the shallow water environment and the excitation mechanism of the seismic wave. Based on the first-order velocity-stress equation, staggered grid finite difference method was taken to discretize the equations. The stress mirror method was applied to deal with free surface of seawater and air. The split boundary perfectly matched layer method was applied to deal with the boundary of the computing area.  The parallel and inclined seafloor seismic wave fields were computed. The results before and after were compared, which shows that if the boundary is not treated, serious reflection would cover up the original wave field characteristics, but after the treatment, each case of wave field wave line and wave propagation rules are quite clear. So this method completely conforms to the shallow water ship seismic wave field numerical simulation requirements.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to improve the operation reliability of oscillator, a novel radiation-hardened-by-design VCO (voltage-controlled-oscillator) using interleaved structure was presented. The VCO consists of multi-stage delay cells which apply interleaved structure and can complete majority decision voter, so it is tolerant to single-event transient effect. Additionally, the VCO can generate symmetric multi-phase output as no additional module for majority decision voter is needed to be introduced in it. The radiation-harden differential VCO was implemented in a 130 nm bulk complementary metal oxide semiconductor process. Simulation results show that, when deposited charges range from 100 fC to 800 fC, the maximum phase displacement generated by a single simulated ion strike for the proposed VCO output is less than 0.35 rad.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The large-capacity data storage device of spacecraft mainly adopts the solid-state storage based on NAND Flash chip. However, due to data bit error caused by the single event upset of the space environment and the threshold voltage deviation during memory operation, the data reliability of the storage device is reduced. According to the physical structure and data structure of the NAND Flash chip, an error detection and correction coding design with RS(256,252)+LDPC(8192,7154) cascade encoder circuit was proposed, for improving the error tolerance of data storage devices. Moreover, the method for circuit realizing of the coding algorithm was optimized. The results of modeling simulation and the ground system testing prove that the solid-state storage controller system has the advantages of low hardware consumption, low power consumption and high reliability. In addition, the total capacity of the storage system reaches 512 Gb, and the effective data throughput is 700 Mb/s, which can meet the design requirements of large-capacity data control and high-data throughput for solid state storage controller of spacecraft.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Crystal oscillator output frequency often drifts under vibration. Therefore, based on the analysis of the acoustic active noise control technology and the mechanism of acceleration effect on crystal oscillator phase noise, a method of reducing crystal oscillator phase noise under vibration was proposed. The simulation about the acoustic active noise control system obtained that the theory of acoustic noise reduction can be used in crystal oscillator phase noise reduction. By adding acceleration sensor, analog-to-digital converter, digital-to-analog converter and digital processor in the peripheral circuit of crystal oscillator, the phase noise real time compensation active noise control system was constructed. The results show that the active noise control system achieves 20 dB phase noise compensation under the random vibration of 0.03g/Hz amplitude range and 10~850 Hz frequency range.·]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A harmonic suppression method with multi-mode fuzzy hysteresis control was proposed for the rapid increase problem of grid harmonics in large-rate rapid charging of battery for electromagnetic launch. Based on the timing series topology of the hybrid energy storage system for electromagnetic launch, the special application conditions and largerate charging strategy of the battery were explained. The topology of the battery charging was introduced, and the source, characteristics and causes of the harmonics were clarified. Based on the analysis of the harmonic characteristics of a single charger, the distribution of harmonic voltage and current of the power grid under different charging currents and the number of chargers were studied. The multi-mode control method and its switching criteria were designed. The simulation model of the charger, instantaneous reactive power detection, harmonic suppression and multi-mode control were established. Simulation and experimental data show that the multi-mode control method can quickly suppress the harmonic abrupt increase of the large-scale start, stop and fluctuation of the chargers, and the compensation effect satisfies the national standards.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Due to the long transmission distance and low power, satellite navigation receivers may not be able to demodulate the message normally in the complex environment. Error correction encodings were commonly used in the navigation message design to improve demodulation performance. With the improvement of technology, more powerful error-correction codes have been adopted in the modernization of GNSS (global navigation satellite system). BDS (BeiDou navigation satellite system ) new signals will adopt M-ary LDPC (low density parity check) encoding. Based on the principle of M-ary LDPC codes, the software simulation and hardware test results of M-ary LDPC codes on BDS were presented. Results show that the 64-ary LDPC codes have high coding gain, and they can outperform about 0.4~0.8 dB over their binary counterparts, which will greatly improve the demodulation performance under harsh environment. The results can provide reference for the development of BDS new receivers.]]></description>

The missile attack envelop was divided into five parts according to the relationship between missile hits and target maneuvers. By analyzing the situation parameters which affect the attack result of air-to-air missile, a missile attack prediction model was constructed. In the experiments, the reconstruction error and the test error rate were used to determine the network structure. Through extracting data layer by layer, the features of parameters were analyzed and the approaches of fine-tuning data sampling were discussed. Back propagation network and support vector machine were selected for classification comparison experiments. The results show that the deep belief network performs better than the other two algorithms in speed and prediction accuracy and the presented method is of great practical value.]]></description>

According to the basic principle of ISRJ, when the jamming with conventional uniformly repeater is applied to wideband imaging radar, a string of uniformly spaced artificial scatters are overlain on the high resolution range profile. The artificial scatters′ characteristic of being uniformly spaced  goes against with the camouflage of jamming signal. In order to solve this problem, based on the conventional ISRJ, a new jamming method using interrupted-sampling un-uniformly repeater, in which the main purpose was broken the uniformly spaced of artificial scatters, was put forward, and the effect of the new jamming method was also analyzed. Finally, by means of simulation, it is found that the new jamming method can promote jamming effect to wideband imaging radar.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[It is now a basic premise to acquire the polarization scattering matrix of radar target accurately before the polarization information processing. Based on a pair of linear frequency modulation signals with opposite slopes and aimed at the simultaneous polarimetric radar adopting the digital dechirp processing, the mathematical model of the influence of the intermediate frequency deviation and sampling frequency deviation on simultaneous polarization measurement was derived. An intermediate frequency deviation and sampling frequency deviation joint estimation and calibration algorithm was proposed. Simulation and real data results show that the radar frequency stability can change the peak position and phase of the simultaneous polarization scattering matrix measurement. The approach proposed can regulate the peak deviation effectively, compensate the phase error and accurately acquire the four elements of polarization scattering matrix.]]></description>
