Forecast of naval vessel sonar self-noise based on radial basis function neural network

A radial basis function neural network has excellent ability of rapid learning and approximation function. In this paper, all the acoustic source factors influencing the naval vessel sonar self-noise are analyzed. By taking naval vessel sonar self-noise as the object function, the radial basis function neural network is used to forecast naval vessel sonar self-noise. The actual data of naval vessel sonar are used to train the network, and then the trained neural network can forecast the naval vessel sonar self-noise accurately.
