摘要
本文分析了通道相位失配对高分辨率参数估计算法MUSIC的统计性能的影响,并提出了一种采用遗传算法对通道相位失配进行修正的新方法。利用遗传算法的全局寻优特性,将它与MUSIC算法有机地结合在一起,实现了对MUSIC算法的通道相位失配的有效修正。最后以八元直线阵为例进行了仿真,验证了这种新方法的可行性和有效性。
The statistic performance of the high resolution parameter estimation algorithm (MUSIC) in the presence of channel phase mismatch is analysed. A new method is put forward by use of genetic algorithms. And it can effectively amend channel phase mismatch. The simulation result testifies its feasibility and validity.
