摘要 提出了基于电磁矢量传感器阵对非相关信源的Capon和Music空间谱的解析表达式.对比基于电磁标量传感器的空间谱,分析了基于矢量传感器阵的DOA(D irection ofArrival)估计方法的改善.根据阵列信号处理原理,对单个电磁矢量传感器分析,并进行DOA估计.通过计算机仿真表明矢量传感器阵对DOA估计比标量传感器阵有更高的分辨能力. Expressions on several spatial spectrum of irrelevant sources such as Capon and Music based on electromagnetic vector sensor array are derived. Compared with the spatial spectrum of scalar sensor array, the improvement of DOA estimating method on the basis of vector sensor array is analyzed. Single electromagnetic vector sensor array is analyzed and DOA estimation in terms of the principles of array signal processing. It is proved that the resolving power of vector sensor array DOA estimation is stronger than that of scalar sensor array through computer emultion.
