摘　　要：鉴于传统的MUSIC(Multiple Signal Classification)算法分辨率不高且在阵元数目较少的情况下对目标信号方位估计不佳等问题,提出了一种基于矢量传感器的改进MUSIC算法。该方法对空间谱函数进行处理,以得到更加优化的方位估计。从阵元数目和分辨角度等方面与传统的MUSIC算法对比,实验仿真表明该算法相对于传统的MUSIC算法有着明显的优越性。In view of the problems of low spatial resolution and poor signal estimation under the circumstances of the array elements with less number in traditional MUSIC algorithm,a modified MUSIC algorithm based on the vector sensor was proposed.The spatial spectrum function was processed by this method to obtain the more accurate position estimation.Compared with the traditional MUSIC algorithm from the aspects of array element number and resolution ratio,the simulation results show that the modified algorithm is superior to the traditional MUSIC algorithm.
