Improved Bearing Resolution Approach for MVDR BeamForming

Abstract

Abstract: Abstract： An approach was proposed to improve the minimum variance distortionless response (MVDR) beamforming bearing resolution by designing an enhancement factor in its weight vector which is known to be a principal factor in resolution improvement under a high signaltonoise ratio (SNR) condition. This method can provide improved bearing resolution not at the expense of the signaltonoise plus interference ratio gain. The simulation results show that this method can effectively improve the MVDR beamforming bearing resolution without losing the signaltonoise plus interference ratio gain.

Key words: Key words： minimum variance distortionless response (MVDR), beamforming (BF), bearing resolution
