摘　　要：在激光制导武器半实物仿真系统中,激光大气传输衰减模型的精度直接决定着整个系统的仿真精度。为给出一种满足工程应用且较简单的、可用于1.064μm激光制导武器半实物仿真的大气衰减模型,基于战场背景环境,综合考虑大气组分的吸收和散射效应,依据天气状况将气溶胶对激光的影响分解为气溶胶(无云无雾情况下)、云、雾、雨、雪和战场烟剂6部分。应用大气对激光辐射的衰减规律,结合一些经验公式,建立了各部分的大气衰减模型。最后利用所建大气衰减模型,计算了几种典型天气条件下大气对激光传输产生的衰减,并与LOWTRAN7计算结果进行了比较和分析,结果表明所建模型是正确有效的。In Hardware-in-the-loop（HWIL） simulation of laser guided weapon systemsthe simulation accuracy of the whole system is directly determined by the laser atmospheric attenuating model.In order to supply a simple laser atmospheric attenuating modelwhich can meet the need of simulationwe divided the aerosol teams into six parts of aerosols（cloudless and fogless）cloudfograinsnow and war-smokebased on the battle-field environment taking into consideration of the absorption and scattering effects of the atmospheric component.The atmospheric attenuating law of laser radiation was used together with some of the empirical formula for establishing the atmospheric attenuating model of each part.Finallythe model was used to calculate the atmospheric attenuation of laser transmission under several typical weather conditions.The result was compared with the calculation result of the LOWTRAN7which showed that the model is correct and effective.
