为了研究电磁脉冲弹对雷达等电子设备的杀伤规律和耦合方式，构建了电磁脉冲弹的杀伤模型，仿真计算了目标区域的覆盖面积、目标点的功率密度和场强振幅。理论分析和实例计算结果表明，电磁脉冲弹的作用效果与爆炸高度、波束角和倾角有关。最后对在目标区域边缘点两种特殊状态下的雷达天线阵面的耦合能量进行了仿真分析，得到了有益的结论，为雷达前门电磁防护设计提供了一定的理论依据。

In order to study the damage rules and coupled modes of the electromagnetic (EM) pulse bomb on radar and other electronic devices , this paper builds up a damage model of EM pulse bomb, simulates and calculates its killing area in target’s region , and the power density and the amplitude of field intensity at target’s point. By theoretical analysis and example calculation, it is shown that the effect of EM pulse bomb is related to the bursting altitude, beam angle and dip-angle. Finally, the coupling energy of radar antenna array under the two kinds of special status at the edge point of target’s region, is simulated and analyzed, by which, some useful conclusions are drawn, thus offering a certain theoretical basis for design of radar front-door’s EM protection.
