摘　　要：应用大气光学理论分析了大气折射及其湍流效应对光电测距精度的影响后认为,光电测距的光束离地面比较高时,必须进行气象参数的代表性误差改正,并且选择大气湍流比较弱的时间进行光电测距。Having Analvzed the influence of atmospheric refraction and turbulence on the accuracy of lightwave ranging with the theory of atmospheric optics, authors consider that the representative errors of meteorological parameters must be corrected when the line of sight is higher above the underlying surface, and ranging must be carried out in the times of that the atmospheric turbulence is weaker.

关 键 词：光电测距 光波测距 大气折射 大气湍流
