摘要
简要概括了无源干扰中的烟幕干扰、以及烟幕的基本知识,分析烟幕的产生、干扰原理,详细介绍了烟幕粒子尺寸分布函数,以及烟幕消光的比尔-朗伯定律。针对1.06μm和10.6μm波长的激光,分析了石墨粒子对其消光特性,仿真显示,在粒子半径变化时,质量消光系数的变化规律,以及由石墨粒子及铜粉粒子组成的烟幕的透过率与烟幕厚度、烟幕浓度的变化规律。
The smoke interference in passive interference and the basic knowledge of smoke are summarized. The generation and the jamming principle of smoke are analyzed. The distribution function of the smoke particle size and Bill Lambert law of smoke extinction are introduced. The extinction characteristic of the graphite particles to 1.06 μm and 10.6 μm wavelength laser is analyzed. Simulation results show the changing laws of mass extinction coefficient, the transmittance of smoke, which is composed of graphite and copper powder particles, smoke thickness and concentration as particles radius changing.
