摘　　要：MUSIC算法是经典的DOA估计算法,且只是一种解决非相干信源测向的超分辨算法,当两个信源完全相干时,MUSIC算法几乎失去分辨能力。因此,本文针对相干信源,研究了几种超分辨算法,进一步给出了仿真分析,最后对各种算法进行仿真对比。MUSIC algorithm is a classical DOA estimation algorithm,and it is only a super-resolution algorithm to solve the direction finding of incoherent sources.When the two sources are completely coherent,the MUSIC algorithm almost loses its resolution.Therefore,concerning coherent sources,some super-resolution algorithms of coherent sources were studied in this paper,and simulation analysis were also further conducted.Finally,various algorithms were simulated and compared.
