Robust adaptive beamforming based on the eigenstructure method
Won Sik Youn, C.K. Un · IEEE Transactions on Signal Processing · 1994
In a linearly constrained beamformer with imperfect arrays, the authors investigate the cause of cancelling the desired signal from a viewpoint based on the eigenstructure properties of the array covariance matrix. Based on this cause, they propose a robust beamforming algorithm. As an adaptive algorithm of the proposed beamformer, the present a data-domain signal subspace updating algorithm.>
