Aiming at the characteristics of underwater acoustic signals and the characteristics of passive sonar target recognition, a self-organized neural network classification algorithm is proposed. The algorithm is mainly aimed at the incomplete sample of underwater acoustic signals. The multi-neuron activation model and self-organization competition learning algorithm are introduced into the former debt neural network, which improves the generalization performance of the passive sonar classification system. The algorithm adopts hierarchical learning strategy, which effectively saves the training time and reduces the probability of falling into the local optimal solution. The experiments on the recognition of real-time passive sonar target signals show that the algorithm has good generalization ability and high recognition rate.
