针对大气气溶胶辐射传输衰减效应是影响1.06μm激光武器系统性能的重要因素,探讨了大气气溶胶对1.06μm激光探测作用距离的影响,构建了激光制导波段探测作用距离模型,并在此基础上进行激光探测作用距离的大气气溶胶影响数值仿真。试验表明,基于该模型计算的大气透过特性准确度基本符合国际公认理论分析值,对作用距离的评估结果与客观实际基本相符,对最大限度分析利用战场气象环境以确保武器作战性能的充分发挥具有重要价值,可为激光探测作用距离的气象环境影响后续发展奠定一定基础。

The laser-guided weapons has become one of the major combat forms, while the meteorological environments seriously restrict the operational effectiveness of it. According to the absorption and scattering of aerosol are the main factors which influence the propagation and attenuation of laser（ 1. 06μm） which is the key facture to the system performance of la- ser weapon, it is necessary to make clear the influence of the aerosol on the laser sensor＇s ability. Through the analysis of the laser （1.06μm） transmission characteristics of the aerosol, the detection performance range for laser sensor＇s ability to detect a target is numerical predicted. This study is significant for the laser-guided weapons to improve the precision and the adaptation of environment.
