非相干分布源2D-DOA与角度扩展估计新方法
New 2D-DOA and Angular Spread Estimation Method for Incoherently Distributed Source
摘要
Abstract
According to the structure covariance matrix, the covariance matrix can be separated into two matrices rebuilt by phase information and amplitude information, respectively. The 2D-DOA could be estimated from the rebuilt phase information matrix by using traditional methods. Based on specially array geometry designation, the angular spread could be estimated by substituting the estimated DOA into the amplitude information vector. Thus such separation realizes separable estimations of 2D-DOA and angular spread for incoherently distributed sources. Computer simulation validated the performance of the method.关键词
