摘　　要：以三个单极子组成的均匀线性阵和三个单极子 \交叉环组成的非线性阵为例 ,通过使用MMUSIC算法分别对他们接收到的包含两个目标的模拟海杂波数据进行处理后提取的目标到达角参数是否正确 ,检验MMUSIC算法对非线性天线阵的适用性 ,得出MMUSIC算法对均匀线性阵适用 ,对非线性阵列不适用的结论 ,并分析了原因 .Using three monopoles array as the example of linear equispaced arrays and three monopole/cross-loops array as the example of nonlinear arrays, MMUSIC algorithm is adopted to process the simulated data received from two kind of arrays on the condition of two sources on the sea. After processing, the DOA(Direction of Arrival) of linear equispaced array which we get, is correct, and of nonlinear array is incorrect. So the conclusion that MMUSIC algorithm is applicable for linear equispaced arrays, but inapplicable for nonlinear arrays is drawn and the reason is also analyzed.
