高功率电磁环境下导弹发射阵地近地面电磁脉冲波形仿真

主要研究在高功率电磁环境下高空核爆到达导弹预设作战阵地近地面时的电磁脉冲环境。首先给出高空核爆电磁脉冲场近地面计算的理论基础，然后分析不同条件下近地面的电磁脉冲环境参数，编程实现了基于时域有限差分算法的电磁脉冲波形数值仿真，完成了多种特定预设战场环境下的电磁脉冲计算，最后给出由于电磁脉冲武器的发展和HEMP波形表述形式变化，给导弹武器系统抗电磁脉冲性能研究带来的影响和新动态趋势。结论认为：应加强对前沿更陡、强度更强电磁脉冲的抵抗能力，防御重点放在机动作战样式方面，提高战地战时抗毁生存能力。

Simulation of Electromagnetic Pulse Waveform over Lossy Ground of Missile Launch Position in the High Power Electromagnetic Circumstance

The electromagnetic field above ground of settled missile launcher produced by an incident electromagnetic pulse plane wave striking the ground plane is described in this paper. The basic theory of the fresnel reflection coefficients and numerical FFT is researched, the electromagnetic pulse parameters is analyzed on the different lossy ground, and the HEMP waveforms of the typical battleground are simulated in terms of the FDTD and matlab, these typical battlegrounds include the southeast tower-launcher, the northwest vertical-tower-launcher and some other silos such as northeast etc. In the end, the influence on the missile system EMP-resist due to the development of EMP-weapon and change of HEMP standard are also discussed in this paper. The results show that the reinforce of rapider and stronger rise time HEMP should be researched, and the emphasis is movable launcher to improve viability of the wartime and battlefield.
