摘要
对天线林立的舰艇而言,电磁脉冲武器已经成为一种潜在的致命威胁,从电磁波大气传播角度削减电磁脉冲能量是降低电磁脉冲武器威胁的一种防御策略。针对常规电磁脉冲武器的性能指标,从Mie散射理论出发分析了不同尺度谱分布下的电磁脉冲传播透过率问题,并给出在一定防御水平上水雾系统通量与雾滴尺度、浓度的关系。计算了典型舰艇防御电磁脉冲威胁的水雾系统构建指标。分析结果表明,由离散雾滴粒子构成的水雾系统能够有效地防御电磁脉冲的威胁。
Electromagnetic pulse weapon （EMP）has become a potentially lethal threat for the warship that surrounded by antenna,it is a strategy measurement to bring down the threat from the electromagnetic waves propagation in the atmosphere which reducing the electromagnetic pulse energy effectively. In accordance with the performance index of electromagnetic pulse weapon, the transmissivity of EMP propagation in the water vapor was analyzed and calculated using Mie scattering theory, and then the relationship between the flux of water vapor system and the particle scale and consistence is described. The construction index of water vapor system defensing the threat of EMP is also calculated. It turned out that the water vapor system which was made up of water particles at different spectral distribution has the ability to defense the threat of the EMP.
