The minimum variance distortionless response (MVDR) beamformer is one of the most common method, minimizes the array output power while constraining the gain to be one at the direction of interest, It has high performance in interference suppression if the array steering vector (ASV) corresponding to the target signal is known accurately, that isn’t guaranteed practically due to the existence of array imperfections.
therefore the performance of MVDR degrades significantly because MVDR is too sensitive to the steering vector mismatches. To compact with this drawback many approaches have been proposed , such Diagonal Loading Method, Worst –case beamforming, Variable diagonal Loading Method, and steering Vector estimation method.
In this paper, we will study this methods and use the MATLAB program to model and compare its performance.
