一种分布式目标波达方向估计方法

摘要

本文提出一种在多径情况下，利用广义阵列流形的特点，通过求解矩阵的广义特征值分解，不用进行谱峰搜索或多维参数搜索，直接由广义特征值得到分布式目标波达方向(DOA)估计的方法。该方法的估计性能对信号源的分布特性优于MUSIC方法。%The paper proposed a blind identification approach to directionof arrival estimation of multipath-induced spatially distributed signals.By using generalized eigenvalue decomposition rather than resort to spectra search or multidimensional parametric search,we get an algorithm for DOA estimation of distributed sources.The simulation studies show that the new method outperforms the MUSIC algorithm by reducing the sensitivity for scenarios with distributed sources.
