强声脉冲对接收机的干扰压制特性仿真

近年来,随着水下等离子体强声技术的突破性进展以及其在管道除垢、污水处理、海洋地质勘探、水下目标探测等领域取得的显著成果和成功应用,为我们提供了一个新思路：采用水下等离子体强声脉冲来干扰鱼雷自导接收系统,直至使其自导接收系统阻塞致盲,达到压制效果。本文分析了某型鱼雷自导接收机电路原理,建立了基于Multisim的接收机预处理电路仿真模型,仿真分析了强声脉冲对接收机预处理的干扰压制特性。研究成果对水下等离子体超宽带脉冲的工程应用具有重要的参考价值,同时,对研究鱼雷接收机系统的抗干扰特性具有一定的借鉴价值。

The simulation of interference suppression characteristics of receiver by high acoustic pulse

In recent years, with strong underwater plasma technology breakthrough and its descaling in pipe, sewage treatment, ocean geological exploration, underwater target detection in the areas of significant achievements and successful application, provides us a new way of thinking: using underwater plasma intensity acoustic pulses with the torpedo homing system, reception to make its homing receiving system blocking blindness, suppressing effect. This paper analyzes the circuit principle of a torpedo homing receiver, establishes a simulation model of the receiver preprocessing circuit based on Multisim, and simulates the jamming and suppression characteristics of the strong sound pulse on the receiver preprocessing. The research results have important reference value for the engineering application of underwater plasma ultra-wideband pulse, and have certain reference value for the research of anti-jamming characteristics of torpedo receiver system.
