一种对相干信号源进行定位的特征——投影算法

A New Eigenanalysis-Projection Algorithm for Localization of the Coherent Sources with Arbitray Geometry Array

本文提出了一种新算法,该算法用来对任意几何排列的阵列所接收到的信号进行处理,可以解决信号源相干时的定位问题.文中从阵列的协方差矩阵的特征结构出发,同时利用信号子空间和噪声子空间、应用投影矩阵的特性,提出了一种新颖的迭代算法.模拟结果证明了该算法的成功.

This paper presents a new algorithm, which can solve the coherent sources localization problem when it is used to process the signal data received by arbitray geometry array. Based on the cigenstructure of array covariance matrix, applying the characteristics of projection matrix, we ultilize both signal subspace and noise subspace, and present a noval iterative approach. Simulation results prove that this method is succesful.
