| 摘要: |
| 针对“泛探”雷达，提出了一种时-空级联目标检测和DOA估计算法，该方法首先利用基于DFT的数字波束形成技术完成阵元空间到波束空间的转换，然后对协方差矩阵的迹做门限检测，最后采用多级维纳滤波的子空间分解法进行到达角估计。仿真结果表明，本文提出方法对比长时间相参积累和单脉冲比幅测向方法具有较好的时域检测和测向能力。 |

| Abstract: |
| A joint time-space target detection and DOA estimation algorithm on ubiquitous radar is proposed. First, data received by antenna array was transformed from array space to beam space by digital beam-forming based on DFT. Then, the time domain detection was performed with the trace of covariance matrix. In the end, the direction of arrival was estimated by multistage Wiener filter. The simulation results show that the method proposed by this paper has a better performance on time domain detection and precision of DOA. |
