Reliability analysis of all-electron fuze communication hole under strong electromagnetic interference
强电磁干扰下全电子引信通信孔的可靠性分析

摘要

全电子引信即电子安全与解除保险装置，其工作原理是升压变压器经逻辑电路控制在短时间内给储能电容器充电，接收起爆信号后，高压开关导通，起爆回路中会快速形成脉冲大电流大电压，引发冲击片雷管爆炸。电磁脉冲武器作为当今电子战常用武器，其辐射频谱可达30MHz至100GHz，脉冲峰值电压可达数万伏每米，脉冲峰值功率可达10GW，并且可通过多种途径，如电源、线缆、引信体、孔缝等方式耦合进入引信内部，这给全电子引信系统的安全性带来了巨大的危害，对全电子引信在强电磁干扰下的可靠度提出了很高的要求。

Abstract

All-electronic fuse is electronic safety and release device, its working principle is that the step-up transformer is controlled by the logic circuit to charge the energy storage capacitor in a short time, after receiving the detonation signal, the high-voltage switch is turned on, and the detonation circuit will quickly form a pulse high current and high voltage, causing the impact sheet detonator to explode. As a commonly used weapon of electronic warfare today, electromagnetic pulse weapons have a radiation spectrum of up to 30MHz to 100GHz, a pulse peak voltage of tens of thousands of volts per meter, and a pulse peak power of up to 10GW, and can be coupled into the fuze through a variety of ways, such as power supply, cable, fuze body, hole, etc., which brings great harm to the safety of the all-electronic fuze system and puts forward high requirements for the reliability of the all-electron fuze under strong electromagnetic interference.
