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 analyses and simulates the MMUSIC algorithm at the beginning. Then discusses the sensor position uncertainties in direction- finding, simulating it with linear array. From formula and simulating result, it can be seen that the sensor position uncertainties can seriously affect the capability of MMUSIC algorithm.
