强电磁脉冲攻击对指挥通信车系统带来重大安全威胁。针对指挥通信车在高空核电磁脉冲(High Altitude Nuclear Electromagnetic Pulse,HEMP)下的电磁耦合问题,通过数值计算研究车辆结构、线缆和天线的电磁耦合响应,实现指挥通信车电磁脉冲效应的量化分析。仿真结果表明,电磁脉冲通过各种途径耦合到指挥通信车的瞬时脉冲信号足以造成电子设备出现干扰甚至损毁,导致执行任务失败。研究结果为指挥通信车系统的电磁脉冲防护设计奠定了基础。

Intensive electromagnetic pulse(EMP) poses a serious threat to the command vehicle system.The effects of high altitude nuclear electromagnetic pulse(HEMP) on the command vehicle is studied.The coupling process of the vehicle structure,cables and antennas is investigated by numerical simulation to implement quantitative analysis for EMP effects on the vehicle.The simulation results show that the transient pulse of EMP coupling into the vehicle by every method is high enough to cause interference or even damage to the electronic equipment,resulting in failure of the execution task.The research gives insight and lays a foundation to the EMP protection design of the command vehicle system.
