- In order to find the directions of coherent signals, a sparsity enhanced beam-forming method is proposed. The mini-mum variance in the proposed method corresponds to the orthogonal relation-ship between the noise subspace and the sparse representation of the received sig-nal vector, whereas the distortless re-sponse 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 out by the iterative reweighted Lp-norm constraint minimiza-tion for direction finding of coherent signals. Simulation results are provided to show that it has better performance than the existing algorithms in presence of co-herent signals.
