3 . the typical wideband high - resolution method - the coherent signal subspace method ( cssm ) is studied 研究了宽带高分辨阵列信号处理的典型算法? ?相干信号子空间算法( cssm ： coherentsignalsubspacemethod ) 。
2.
We analyzed its nature of resolving coherent sources and compared the influence of different focusing matrices . simulations are conducted to test the performance of these focusing matrices . 4 分析了cssm方法分辨相干源的实质，即通过频域平均消除了相关函数矩阵的奇异性；分析比较了几种不同聚焦矩阵对算法性能的影响。
