| 摘 要： | 水雾干扰波段宽，使用成本低，对生物和环境都不产生毒副作用，是一种新型的干扰材料。利用Mie散射理论，对粒径服从对数正态分布和正态分布的水雾在可见光波段、红外传输大气窗口和两种常用的军用激光波长处的质量消光系数进行了计算，得到了水雾在这些波段(波长)处的遮蔽性能，分析了计算结果与粒径分布参数之间的关系。

| Abstract: | The water fog is a novel jamming material with wider jamming band, cheap cost and non side effect to the creature and environment. Using the Mie Scattering Theory, mass extinction coefficients (MEC) of the water fog with lognormal distribution and normal distribution are calculated in visible-light band, in IR transmission windows and at two military laser wavelengths. The extinction characteristics of the above bands and the lengths are obtained. The relationship between the calculated results and the parameters of the size distribution is analyzed. |
