车辆外部电磁环境分析

车辆外部的电磁环境主要受到电磁脉冲武器源的特性和地面因素的影响,因此以高空核电磁脉冲武器为例从武器的作用范围、功率和能量、地面参数等方面入手,对影响车辆外部电磁脉冲环境的因素进行分析。仿真结果表明：高空核电磁脉冲的作用范围可由爆高计算得出,在中国领土覆盖范围内,北纬30°-60°范围内的电场极化方式以水平极化为主,在北纬4°-30°范围内的电场的极化方式以垂直极化为主。随着地面电导率的增加水平场强峰值不变,垂直电场强度峰值增大,总场强峰值在大地电导率为0.1时最大,对绝大多数土壤来说,含有机物粘土的电场强度峰值最大。

The Analysis of Electromagnetic Environment Outside Vehicles

The electromagnetic environment outside vehicles was affected by the characteristics of electromagnetic pulse and the ground factors primarily. Therefore take the high altitude nuclear electromagnetic pulse as an example,the analysis was taken from the scope, power and energy,ground parameters in this paper. The simulation results show that the range can be calculated by the height of high altitude nuclear electromagnetic pulse,the electric field polarization is mainly horizontal polarization in the north latitude 30° to 60° and mainly the vertical polarization in the north latitude 4° to 30° in China. The peak horizontal field intensity is constant while peak vertical electric field intensity increases with the increasing of ground conductivity. The total peaks field intensity is the highest when the ground conductivity is 0.1 and in clay-containing organic in most soils.
