In order to find the directions of coherent signals, a sparsity enhanced beamforming method is proposed. The minimum variance in the proposed method corresponds to the orthogonal relationship between the noise subspace and the sparse representation of the received signal vector, whereas the distortless response corresponds to the non-orthogonal relationship between the signal subspace and the sparse representation of the received signal vector. The proposed sparsity enhanced method is carried
