Implementation of On-land Simulation of Torpedo Active Ultrasonic Fuze

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.
