    Abstract
  • Most existing underwater target simulators for sonar and torpedo homing system were designed without considering the characteristics of transducer array for signal receiving. To test comprehensively the performance of torpedo homing system in laboratory, we designed and implemented a target simulator with acoustic coupling, including the array element signal simulator and acoustic coupling device. This paper introduces the architecture and functions of the target simulator with acoustic coupling, the hardware platform development of a multi-DSP parallel processing system, the designs of acoustic coupling array and transducer array elements, and the selection of acoustic coupling material. The performance test for the developed target simulator was conducted and the coupled element signals were tested with the existing torpedo homing system. The results verify the feasibility and effectiveness of the target simulator with acoustic coupling. This target simulator can overcome the influence of inexactly modelling transducer array, and reduce the number of underwater tests for torpedo homing system.
