Abstract: Based on the ESB method, this paper presents a novel beamforming algorithm for the uniform linear array which constructs a special matrix instead of the convariance matrix. The algorithm can overcome the problem that the ESB can not work n the environment of coherent signals. Moreover, the algorithm can converge rapidly and keep a good performance in a low SNR and a little snaphshots.
