摘要/Abstract

摘要： 为了充分利用电磁矢量传感器阵列数据中存在的多维结构，本文探讨了具有多维数据结构的电磁矢量传感器阵列多模张量模型的建立，以及模R信号子空间的定义，提出一种基于模R信号子空间投影的MUSIC算法.分析表明:由于模R投影方法可充分利用电磁矢量传感器阵列中的多维结构信息，从而可提高信号子空间的估计精度，进而可使MUSIC算法的性能得以改善.计算机的仿真研究验证了模R投影MUSIC算法明显优于传统MUSIC方法.

关键词: 波达角估计, 阵列信号处理, 电磁矢量传感器

Abstract: This paper proposes a multidimensional (multi-mode) tensor model for the electromagnetic vector-sensor (EMVS) array to make full use of the multidimensional structure of the data.The mode-R signal subspace is defined based on this model.With the projection to the mode-R signal subspaces,a novel algorithm,which incorporates the refined signal subspace and the traditional MUSIC algorithm,is then presented.The proposed technique exploits the inherent multidimensional structure information for increased parameter estimation accuracy.Simulations show the superiority of the proposed algorithm to the traditional one.

Key words: direction-of-arrival estimation, array signal processing, electromagnetic vector-sensor
