Abstract

Abstract

The linearly constrained adaptive beamformer is hypersensitive to the amplitude and phase errors of antenna array when the signal-to-noise ratio exceeds a certain threshold. Even if the array imperfections are slight, the beamformer suppresses the desired signals as if they are interference signals. In this paper, a robust adaptive beamformer in the presence of array imperfections is presented by improving the block matrix of the generalized side lobe canceller. Since this method is based on the structure of the generalize side lobe canceller, it is convenient to use its partial adaptive processing to reduce the computation load.
