加固计算机接口的强电磁脉冲防护研究

Research on EMP Protection for Rugged Computers

针对强电磁脉冲对加固计算机日益严重的威胁,首先介绍了三类典型强电磁脉冲,总结了强电磁脉冲在时域和频域的特点;然后结合加固计算机的结构以及强电磁脉冲的特点、耦合途径,分析了其对加固计算机的毁伤方式;最后基于上述分析,提出了加固计算机接口的能量域-频率域复合多级强电磁脉冲防护方案。

With the increasing threat of Electromagnetic Pulse(EMP)to rugged computers,in this paper,3 typical EMP are introduced firstly,their characteristics in time domain and frequency domain is concluded.Based on the coupling effects of EMP,EMP damage analysis specifically is conducted to rugged computers.Finally,a multi-level protection scheme with cascaded circuits in energy-frequency domain is proposed.
