combined with characteristics of compressed sensing( CS) theory
and this method has features of fast operating speed and high resolution. Simulation results verify the feasibility and effectiveness of the proposed algorithm by comparing with conventional beamforming( CBF) and minimum variance distortionless response( MVDR) algorithms through operation time
