Applying the unit circle constraint to the diagonally loaded minimum variance distortionless response beamformer

Adaptive beamformers (ABF) are used when estimating the direction of arrival of a narrowband planewave with a uniform line array in an environment with loud, unwanted signals. Capon's minimum variance distortionless response (MVDR) suppresses interferers by steering beampattern nulls in their direct…
