多重信号分类算法测向精度的仿真分析

Analysis of the Performance of MUSIC Algorithm for Direction Finding

摘要:

作为空间谱估计理论体系中的标志性算法,多重信号分类算法从1979年提出后就一直是阵列信号处理领域的研究热点之一。针对复杂电磁环境中阵列测向的实际应用问题,从多信源、含噪宽带信号、入射角度、阵列间距这4个因素对多重信号分类算法的测向精度作了仿真分析,得出了一些结论。

Abstract:

As the landmark algorithm of space spectrum estimation, multiple signal classification method has been one of the research focuses to the array signal processing community since proposed in 1979. To deal with the application problems in the complex electromagnetic environment, the performance of MUSIC algorithm for direction finding was analyzed from these aspects such as multiple signals, noisy wide-band signals, the incidence angle, and the array elements spacing. Some conclusions had been drawn, which could provide the reference for the introduction of MUSIC method into the electronic reconnaissance.
