摘要: 鱼雷主动超声引信陆上仿真是全雷陆上仿真的重要组成部分。文中通过对鱼雷主动超声引信回波与各种干扰模型的研究与分析，并将此模型合成应用到鱼雷主动超声引信陆上仿真试验中,同时设计了一种声对接阵形式与基于面向仪器系统的PCI扩展（PXI）测控总线的波形采集和回放模块，构建了鱼雷主动超声引信陆上仿真试验平台,仿真电路实现模块化设计，对于不同类型鱼雷的主动超声引信仿真具有一定的通用性, 通过与声引信产品对接试验证明,所推导的模型正确性和仿真方法的有效性。Abstract: On-land simulation of torpedo active ultrasonic fuze is an important part of torpedo on-land simulation. This paper analyzes the echo of torpedo active ultrasonic fuze and the interference models, and applies these models to on-land simulation experiment of torpedo active ultrasonic fuze. Moreover, a module of waveform collection and retransmission based on on-land test simulation system PCI eXtensions for instrumentation(PXI) test bus and acoustical butted array is designed, and an on-land test simulation system for torpedo active ultrasonic fuze is built. The simulation circuit adopts general modularized design. The correctness of the model and the validity of the simulation method are proved by the experiment of ultrasonic fuze product.
