| 摘 要： | 首先阐述了阵列信号处理中广泛采用的MMUSIC算法的基本原理，然后分析了信源数目欠估计情况下的MMUSIC算法性能。为了解决信源数目欠估计下出现的谱峰消失的问题，讨论了一种改进的MMUSIC算法，并将改进的算法成功运用于相干信号，计算机仿真结果证明该改进算法是有效的。

| Abstract: | This paper introduces the basic principle of MMUSIC algorithm,which is widely applied in array signal processing,analyzes the performance of MMUSIC algorithm while the source number under-estimated.In order to resolve the disappearance of some peaks of MMUSIC spectrum when the source number is under-estimated,discusses a modified MMUSIC algorithm,and applies it in coherent signal successfully.Computer simulation results show that the modified algorithm is effective. |
