Abstract:

The spatial signal DOA estimation problem is investigated based on compressive sensing in this paper.For the problem in DOA of spatial signals that the ordinarily algorithms need a large number of sampling and can't gain ideal effect in condition of low SNR.A multi-vectors focal undetermined system solver (MFOCUSS) DOA algorithm based on singular value decomposition in proposed in this paper.The algorithm overcomes the defect that sparse reconstruction algorithms cannot be used in a low SNR case,and has a lower computational complexity.Experimental simulations show that the presented algorithm in this paper performs better than traditional DOA algorithms for signals with any coherence.
