摘　　要：在阵列信号处理中,为了正确接收信号,在知道信源数的情况下,必须要知道信号的来波方向.分析了在阵列信号处理中用于估计来波方向(DOA)的MUSIC方法和Capon方法原理及算法的实现过程,用Matlab仿真实验,比较两种算法在无噪声和有噪声情况下的性能.The direction of source arrival must be estimated before knowing the source number in order to correctly receive source signals in the array. In the paper,the theory of MUSIC and Capon algorithm for direction of arrival and the implementation of two algorithms are analyzed. Finally, the performances of two algorithms are compared under matlab simulation.

关 键 词：阵列信号 波迭方向 信号源数
