Abstract
Beamformers and beamforming methods involve diagonal loading (regularization). Significant features include the automatic determination of the regularization parameter using a linearly constrained minimum power (LCMP) bounded perturbation regularization (BPR) approach. More specifically, the method has the advantage of efficient beamforming when the desired signal is from a moving source. After determining an initial regularization parameter, each data window (i.e., snapshot) uses the regularization parameter of the prior window to recursively determine the next regularization parameter.
