协方差矩阵的权微扰算法

A Weight Perturbation Algorithm of the Covariance Matrix

本文给出了一种获得协方差矩阵的算法，只需依据自适应阵的输出功率，使用权微扰的方法，就可得到阵列的协方差矩阵。

An algorithm to obtain the covariance matrix is presented. Only based on the adaptive array ouutput power,the array covariance matrix can be obtained by a weight perturbation method.
