Abstract
A frequency-domain partially adaptive beamformer is proposed to reduce the computational complexity of conventional frequency-domain adaptive beamform ers. The proposed beamformer only adapts the weights that correspond to the frequency bins expected to contain interferences using a cell-averaging co nstant false alarm rate (CA-CFAR) processor. The false alarm rate is also c hanged adaptively to achieve optimum partial adaptation. (C) 2001 Elsevier Science B.V. All rights reserved.
