基于奇异值分解和相干积累的DOA估计方法
Method of DOA Estimation Based on Singular Value Decomposition and Coherent Accumulation
摘要
Abstract
This paper briefly introduces the disadvantages of conventional spectrum estimation algorithms when dealing with coherent sources and several common methods of single snapshot DOA estimation,and then analyzes the single snapshot DOA estimation method with the model of array signal.On this basis,a novel DOA estimation method based on the singular value decomposition (SVD) and coherent accumulation of snapshots is proposed.The theoretical analysis and simulation test results show that this method can make the coherent sources de⁃correlated with single snapshot data or data of coherent accumulation,reduce the root mean square error of DOA estimation,and improve the probability of successful separation.关键词
