A Robust MVDR Adaptive Beamforming Method on Time-domain Analysis Signals Wanga,

摘要

Since the MVDR (Minimum Variance Distortionless Response)adaptive beamforming method has poor performance when applied on wide-band passive sonar systems in the present of fast-moving targets, a time-domain analysis method (TAMVDR) has been designed. The optimum solution of TAMVDR method could be obtained with one snapshot data via introducing complex weights on the basis of constructing time domain analysis signal. Out-sea experiment show the performance of TAMVDR method proposed in this paper.
