摘　　要：阵列信号处理是信号处理领域内的重要内容,近年来发展十分迅速,波达方向DOA(Direction of Arrival)估计作为其主要研究方向,在雷达、通信、声纳、地震学等领域内有着非常广阔的应用前景,对高分辨DOA估计算法研究取得了很多重要成果.主要研究经典MUSIC(Multiple signal Classification)多重信号分类算法,并对影响估计性能的各种因素进行仿真分析,为进一步研究MUSIC算法提供参考.As an important part in the field of signal processing, array signal processing develops rapidly in re- cent years. Direction DOA （ Direction of Arrival） estimation is a key research in array signal processing, which has a broad prospect of application in radar, communication, sonar, seismology and other fields. The high reso- lution DOA estimation algorithm has achieved many important results. In the paper, we studied and analyzed the classical MUSIC （ Multiple Signal Classification） algorithm, and the various factors to the estimation performance of the simulation, which provides the reference for the further study of MUSIC algorithm.
