Abstract

Abstract

A new method for Direction of Arriving (DOA) Estimation-Phase Matched Theory (PMT) is introduced, which computation complexity is simple and performance is unaffected by unknown correlated noise. Compared with energy criterion, a robust criterion based on SVD improves the bias and variance of estimation and the simplicity is still kept. Computer simulation shows that the criterions performance approximates MUSIC algorithm at high SNR and exceeds it at low SNR. Specially, this algorithm still has good performance under unknown correlated noise.
