| 摘要: |
| 本文提出了一种基于目标斜距两次测量值之差和方位角信息的定位跟踪算法，详细分析了该技术的定位原理和可行性。在辐射源匀速直线运动的条件下，如果能够不测俯仰角而只用方位角和距离差实现对目标的定位与跟踪，将不仅可以简化接收站的设备，而且还能够增强其独立性能，因此本文讨论的算法对于单站被动定位跟踪系统的实用性具有重要意义。本文通过典型目标航迹的计算机仿真，对算法的性能做了评估。 |

| Abstract: |
| The paper presents a 3-D location and tracking algorithm based on the emitter's distance difference between two measurements and azimuth message. 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. |
