Abstract: An adaptive blind beamforming algorithm for arbitrary underwater array was presented m this paper according to the characteristic of underwater acoustic environment and signal. Doppler information of underwater acoustic signal is used to estimate weights of beamformer without array manifold and a neural network is introduced to carry out the blind beamforming. It can not only avoid computing the inverse of a matrix but also enables the realization of the blind optimizing beamforming through hardwares. And it is demonstrated via analysis and simulation that this method is robust to system error and has the advantage of rapid convergence rate.
