Research on underwater acoustical echo simulation based on lab windows/CVI

摘要

This paper analyzes and researches the underwater target echo property and echo simulation based on the actual need of underwater acoustical signal. Aimed to the complicated marine environmental condition and the properties of underwater acoustical echo signal, We set up the models of the underwater acoustic signal simulation in this paper. After the analysis and modeling of underwater acoustic echo simulation, the underwater acoustic signal generation and echo simulation software is designed by using Lab Windows/CVI software. Its feasibility and satisfied underwater acoustical echo signal simulations have been verified through pond trail in operation laboratory.
