【Abstract】 This paper focuses on the research of the system structure of the synthetic environment of the passive sonar and the modeling and simulation test of the underwater sound synthetic signal. Based on the example of moving underwater target, the model of synthetic signal, environment noise and ocean acoustics are shown. The synthetic system simulation tests are presented in the underwater sound environment, respectively. The research result can be applied to the environment simulation of the underwater detecting system and underwater acoustic warfare system, as well as evaluation of the underwater sound equipment.更多还原
