Finally，it is pointed out that due to the constraints of current technical conditions and the complex underwater environment，this method still has shortcomings. This mehod provides a reference for further optimization of deep learning algorithms，expansion of the scope of deep learning technology applications，and improvement of underwater acoustic target recognition efficiency.
