Design and Implementation of a New Type of Underwater Acoustic Target Simulator

Abstract:

According to the actual needs of underwater acoustic homing system in system debugging and experiment parameters setting, a new design of real-time water target simulator is introduced. This system simulates the acoustic reflection characteristics of targets, receives active detection signal and emits signals of reflection echo characteristics. The target simulator can response up to two active detection signals in the condition of interference. This system is complete, accurate and can be extended. Users can monitor the working state of simulator and change the parameters of simulator. As a result of an echoic tank experiment and lake experiment, the system has been successfully applied to the underwater homing system.
