Abstract

In this correspondence, three methods are proposed to design the look-direction amplitude/phase response to optimize the Frost beamformer. With some constrained optimization criteria, the new constraint vector and thus the new weight vector are designed to improve the output signal-to-interference-plus-noise ratio (SINR) relative to the beamformer with the distortionless constraint. Simulation results are presented to demonstrate the improved interference and noise suppression performance of the optimized beamformer
