| 摘 要： | 本文分析了平面阵接收信号的协方差矩阵，发现它可分解为一个广义对称矩阵与一个非广义对称矩阵之和，利用信号协方差矩阵的这一结构特征，重点研究了相干源二维波达方向（DOA）估计．该方法通过构造一个差矩阵，求出其本特征值对应的任一特征向量，利用谱函数估计相干源二维DOA．简要分析了二维DOA估计的分维处理。

| Abstract: | In this paper, the covariance matrix of signals received by a planar array is analysed and it is the sum of a persymmetric and a non-Persymmetric matrices . The two-dimensional (2-D) direction of arrival (DOA) estimation of coherent signals is studied based on this property of the covariance matrix . The defference matrix is made and any one of eigenvectors corresponding to the zero eigenvalue is computed . The 2-D DOA is estimated using the spectrum function . The separable dimensional approach for 2-D DOA estimation is simplyanalysed. |
