摘要

摘要: 现有的大多数水下目标模拟器(包括针对声纳和鱼雷自导)在设计时均未考虑信号接收端的换能器基阵特性, 为能在陆上试验室条件下全面测试鱼雷自导系统性能, 设计并实现了一种基于声对接方式的鱼雷自导目标模拟器, 介绍了声对接式目标模拟器的组成及其相应功能, 设计了阵元信号模拟器与声对接装置, 完成了并行处理系统的硬件开发、声对接基阵与换能器阵元设计及声匹配材料的选取。通过对研制的声对接式目标模拟器的性能测试, 并利用自导头通过声耦合对生成的阵元信号进行检验, 结果证实了以声对接方式设计并实现的目标模拟器的可行性和有效性。该目标模拟器克服了对声学部件建模不精确所带来的影响, 减少了鱼雷自导系统水下试验的次数, 具有很好的实用价值。

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.
