Description
Summary:Aiming at the DOA estimation when some elements in the hydrophone array fail, the conventional beamforming algorithm is not effective in estimating the direction of arrival. This paper proposes a beamforming algorithm based on greedy recovery. The ideal conditions and After the estimation effect under the failure condition of the array element, the detection performance of the method is compared and analyzed by simulation. The results show that when the failure ratio of the array element reaches 70% or more, the method always keeps the effective identification of the direction of arrival, and has better detection performance and tolerance than traditional algorithms.
