Abstract

Sonar signal processing simulator is used for simulating ship-radiated noise received by hydrophones in different marine environment. Application of the simulator will greatly reduce the frequency of experiments on lakes or seas, and shorten the development cycle for sonar device. Considering the falling tendency of continuous spectrum of the ship-radiated and ocean ambient noise, a towed linear array sonar signal processing simulator is proposed in this article, which could obtain accurate computation of the continuous spectrum level at different frequencies, and simulate variation of amplitude with frequency. Accuracy of the simulated hydrophone data is proved through numerical simulation. The simulator designed provides more flexibility since the configuration parameters are available, which could give analog output of underwater sensor data for towed linear sonar with different designed frequency or number of hydrophones. The simulator can be applied to examining performance of sonar system, which is valuable to engineering application.
