中文摘要：
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。
英文摘要：
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.
