中文摘要：
针对雷达系统作了防电磁干扰能力的判定,同时对战场中逐渐占据主体的典型电磁波的类型及其干扰程度作了分析。为了探究电磁脉冲对电子器件的损伤机理,用不同脉宽的方波脉冲对LM324N、CD4069UB进行了注入实验,发现器件电路损伤在很大程度上与脉冲能量的大小有关,存在一个由绝热过程向热平衡转化的阶段,验证了电磁脉冲对电子器件的绝热烧毁效应。针对雷达系统提出了综合的电磁防护原则。
英文摘要：
The ability of the radar system against electromagnetic interference is determined, and the type and interference degree of the typical electromagnetic wave are introduced. In order to explore the electromagnetic pulse＇s effect on the electronic device, the experiments on LM324N and CD4069UB with the square-wave pulse of different width are done,in which it is found that the device circuit＇s damageis related to the magnitude of pulse energy to a great extent,and there is a phase from adiabatic course to thermal-balance course. The effect of the adiabatic burning on the electronic device caused by the electromagnetic pulse is verified. The electromagnetic protection principle is proposed.
