一种电磁脉冲前门耦合效应的事件分解评估方法

摘要

电磁脉冲弹是一种利用辐射高功率电磁脉冲干扰/毁伤目标电子系统的新概念武器.为计算电磁脉冲通过前门耦合毁伤目标的效能,提出一种基于事件分解的效能评估方法,按时间序列将前门耦合-毁伤过程分为弹体爆炸辐射电磁脉冲、大气传输衰减、目标系统耦合3个子事件,分别用不同算法计算其发生效能.用该方法对美国MK84导弹搭载的电磁脉冲弹进行评估,得到具有一定参考价值的效能评估值.%Electromagnetic pulse (EMP) bomb is a kind of new concept weapon,which can be used to disturb or damage electronic system by radiating high power electromagnetic pulse. To calculate damage efficiency of high power EMP through front-door coupling, a kind of efficiency evaluation method based on affair-decomposability is raised. Front-door coupling - damage course is decomposed into three affairs in chronological sequence, which is EMP bomb radiating power, electromagnetic energy transmission and electromagnetic energy coupling into target system. Efficiency of these three affairs is calculated with different algorithms. Finally, type MK 84 electromagnetic pulse bomb of USA is evaluated using this method. Some conclusions about efficiency evaluation are gotten.
