Discussion of Torpedo Acoustic Homing Operation in the Shallow Water

The performance of torpedo homing system is affected by the high reverberation interference and multi-path effect in acoustic environment of the shallow water.This paper analyzes three negative influences of the shallow water environment on torpedo acoustic homing,and provides approaches to improve the homing performance.It also discusses the wideband array mode,signal design,signal receiving and processing,and self-adaptive techniques.The simulation result shows that the torpedo homing performance in the shallow water can be improved effectively through optimization design of signal waveform and detection algorithm,and application self-adaptive techniques.
