激光致盲武器雨雾条件下传输机理研究

非致命激光致盲武器在恶劣天气尤其是雨雾天气下使用时,打击效果较差,不能达到预期的致盲效果。因此,必须研究一种激光自动调节系统,而设计这个系统最关键的问题就是研究激光在雨雾条件下的传输机理,所以本文基于Mie散射理论分别研究了激光在雨中、雾中以及雨雾共存三种条件下的衰减情况,得到激光透过率与降雨量、雾浓度以及传输距离之间的关系。对其进行Matlab仿真,结果表明激光透过率随着降雨量的增大、雾浓度以及传输距离的增加而减小,且衰减明显。

Research on attenuation mechanism of non-lethal laser blinding weapon in rain and fog

Combat effect of non lethal laser blinding weapons is poor in inclement weather,especially in rain and fog,and it can not achieve the desired operation effect.Therefore,a laser automatic regulating system must be developed,and the key part of the effort is to study the transmission mechanism of the laser in the rain and fog.Based on the Mie scattering theory,laser attenuations is studied under three conditions in the rain,fog,rain and fog,and the relationship between laser transmittance and the rainfall,the fog concentration and the transmission distance.The Matlab simulation results show that the laser transmittance decreases with the increase of rainfall,the fog concentration and the transmission distance,and the attenuation is serious.
