【摘要】 讨论了基于电磁矢量阵列的相干和非相干分布源信号模型,在此基础上提出了针对相干分布源信号的极化MUSIC和针对非相干分布源信号的部分极化MUSIC两种二维波达方向估计方法。论文还研究了非相干分布条件下阵列输出协方差矩阵特征值与分布源角度和阵元数的关系。计算法仿真结果表明本文方法是有效的。更多还原

【Abstract】 A polarimetric distributed source model is established for an electromagnetic vector sensor array.Two types of MU- SIC-like methods are proposed for 2D direction of arrival estimation of coherent and incoherent distributed sources,respectively. The relation between the eigenvalues of covariance matrix and angular extend and number of elements is examined.Simulation results are included to verify the efficacy of the proposed methods.更多还原
