摘　　要：首先对MMUSIC算法进行了分析和仿真,然后重点讨论了阵元位置误差对MMUSIC算法测向性能的影响,并以均匀直线阵为例进行了仿真实验。从理论推导和仿真结果可以看出,天线阵阵元位置误差严重影响着MMUSIC算法测向性能,得出了有用结论。This paper firstly analyzes and simulates the MMUSIC algorithm,then focuses on discussing the influence of array element position error on direction finding performance of MMUSIC algorithm,and makes the simulation test taking the linear array as an example. It can be seen from the theory deduction and simulative result that the array element position error can seriously affect the direction finding performance of MMUSIC algorithm,and the useful conclusion is obtained.
