Characteristics Modeling and Simulation of Ship-Radiated Noise

Abstract

Since the importance of ship-radiated noise simulation in onshore simulation training and digital sonar development, we establish a mathematical model of ship-radiated noise on the basis of analyzing the causes and characteristics for each of its components, and then apply the model on simulating each signal component in turn. Additionally, for improving the versatility of the model while reducing the complexity of the simulation, a design method for specific frequency response filter based on window function is used to realize the simulation. The simulation results demonstrate the effectiveness of the approach.
