摘要

针对电磁矢量传感器阵列信号波达方向(DOA)估计问题

提出了一种基于张量模型的双模MUSIC算法

并讨论了双模MUSIC角度参数和极化参数的分离问题

提出一种低维双模MUSIC算法.(低维)双模MUSIC算法利用了张量信号子空间与两个噪声子空间的双模正交性

通过连续两次子空间投影完成DOA估计.计算机仿真结果表明

(低维)双模MUSIC算法性能要明显优于传统基于矩阵模型的MUSIC方法.

Abstract

This paper considered the problem of direction of arrival(DOA)estimation with electromagnetic vector sensor arrays

and proposed the dual mode MUSIC(DM-MUSIC)algorithm based on the tensor model.Decoupling of direction and polarization parameters is also addressed

based on which a lower dimensional DM-MUSIC algorithm is proposed.(Lower dimensional)DM-MUSIC exploits the dual mode orthogonality of tensor signal subspace and two noise subspaces

and accomplishes DOA estimation by two consecutive projections.The simulation results exhibit the superiority of(lower dimensional)DM-MUSIC to the conventional MUSIC.
