| 摘 要： | 多输入多输出(Multiple-Input Multiple-Output:MIMO)雷达利用多天线发射互相正交的信号,可以实现灵活的发射分集设计,具有高分辨率的空间谱估计性能。为降低计算的复杂度,提升信噪比高时信号的性能,文章基于MUSIC算法对双基站雷达信号的到达角与发射角作相应估计,结合优化方法和误差准则,对不同参数条件下的该算法作了仿真分析和综合比较。结果证明了该算法的有效性。

| Abstract: | Multiple-input-multiple-output(MIMO) radar,which utilize multiple antennas to simultaneously transmit orthogonal signals,offers flexible design of transmit diversity and high resolution of spatial spectrum estimation.To reduce the calculating complexity and enhance the signal quality at high SNR(Signal to Noise Ratio),a direction of departure(DOD) and direction of arrival(DOA) estimation algorithm is proposed in bistatic MIMO radar based on MUSIC estimation algorithm.Combined with optimization method and error criterion,simulation analysis and comprehensive comparison has been made for this algorithm in different parameter condition,and the results demonstrate its effectiveness and robustness. |
