中文摘要	光束通过大气时,由于大气密度的不均匀性使光束发生偏折,光传播的程长增加及其轨迹产生弯曲,由此造成待测目标的角位置和距离的测量误差.分析了近几年新疆戈壁地区大气参数探空数据的主要结果,给出了大气参数的平均高度分布廓线,依据光波波段的折射率公式,利用以上结果计算了该地区折射率高度分布数据,通过模式拟合给出了该地区大气折射率指数分布模式和三参数伽马分布模式.详细分析了大气压强、温度、波长等因素单独对大气折射率的影响.应用该地区的大气折射率高度分布模式对光传输的大气折射效应进行了理论分析,给出了整层激光传输的折射角、蒙气差和大气色散.以期对该地区光传输折射效应进行修正.
英文摘要	When beam wave propagates through the non-homogenous atmosphere,the beams are refracted,optical path is increased and the track is curved,hence the measuring error is caused by angular position and distance of tested targe.Some main experimental datum of the atmosphere parameters were obtained in desert of Xinjiang.According to the measuring data,the atmospheric refractive index characteristics at various heights were summarized,and the measuring profiles of the atmospheric refractive index were given.Exponential distributing mode and three-parameters-gamma distributing mode of the atmospheric refractive index were given by mode fitting.Influence of factors such as pressure,temperature and wavelength on the atmospheric refractive index were analyzed.Based on the modeling profiles of the atmospheric refractive index,the effect of atmosphere refractive of optical propogation was analyzed in theory,the refractive angles and dispersion angles were calculated as beams propagated through the atmosphere at different zenith on typical wavelength.Calculation results provide reference for correction of the refractive effects on beams propagation.
