Robust Adaptive Beamforming Based on Convex Optimization with Variable Diagonal Loading

Many approaches was proposed to improve the robustness of the adaptive beamforrner, such as minimum variance distortionless response (MVDR) beamformer against array steering vector errors. In this letter, a novel robust adaptive beamformer based on convex optimization is proposed, and its performance was compared with other beamformers, and we used matlab to demonstrate its robustness against mismatch in steering vector.
