The atmospheric transmission property of 1.06 μm laser is analyzed by using the Modtran model, and some valuable conclusions and inferences are presented. The effects of atmospheric molecules, aerosol, fog, rain, visibility and different path are considered. It is pointed out that,in the course of the atmospheric transmission of 1.06 μm laser,the impact of molecules can be neglected. The effect of aerosol is more obvious and the transmission is reducing with the decrease of visibility especially when the visibility is less than 10 km. At the same time,the 1.06 μm laser can hardly pass through the atmosphere when it is fogy or heavily raining day. The conclusions above have positive significance when the laser-guidod weapons are developed,experimented and used in the war.%利用Modtran大气辐射传输模型,分析大气环境对1.06 μm激光透过特性的影响,包括大气分子,气溶胶,雾,降雨,水平能见度以及不同的探测路径对1.06μm激光透过特性的影响.研究表明,1.06μm激光在大气传输中大气分子吸收效果非常小,基本可忽略不计;气溶胶对其的影响则较大,且透过率随着能见度的降低而减小;雾和降雨对激光的衰减作用非常明显,在大雾或者中雨大雨的条件下,激光的透过率非常小,基本很难通过.这些结论对于1.06μm激光制导武器的论证、研制、仿真和作战具有积极的意义.
