摘要：
Underwater environment is more complex than the air and underwater acoustic signals are often hidden in the noise. Therefor, the interest signal needs to be enhanced or selected before identifying. In this paper, the signal is first enhanced by the method of beamforming, and then the acoustic signal feature is extracted and sent to softmax for recognition. The effectiveness of the method is verified by experiments.
