本文主要是对 DOA（波达方向）估计中传统 MUSIC 算法及其改进算法作了简要

的介绍，然后通过仿真比较了这几种算法的优缺点以及各自的适用范围，最后给出了嵌入式

系统实现的设计思路及流程图，并指出以后的研究重点。-The article introduces the research and implementation of MUSIC algorithm in DOA estimation briefly.

Firstly, it introduces the background of the study to DOA and indicates the importance of DOA

estimation　secondly, it gives the traditional MUSIC algorithm and some advanced algorithms. Then,

compare the advantages and disadvantages of these algorithms respectively. Finally, describe the

programming chart in the implementation of embedded system.
