摘　　要：为获得双波长卫星激光测距的最佳波长组合,考虑了大气效应、接收光电器件的响应、激光器等因素,从大气改正精度出发,利用激光雷达方程,得到了评价波长组合优劣的波长优数公式。分别对倍频和喇曼频移两种技术产生的各种波长组合的波长优数进行计算。分析和讨论了在开展双波长可选波长组合的情况,为最佳波长的选择提供了一定的依据和标准。In order to get the optimal wavelength pairs for two-color satellite laser ranging, with the factors including atmosphere effect, the response of the receiver and the laser considered, beginning with the precision of atmosphere correction, based on the lidar equation ,the wavelength figure of merit ,which can determine whether the pair is selected properly, is obtained. Various figure of merits of the wavelength pairs induced by the technology of harmony and Raman scattering is calculated, the possible wavelength pairs are discussed. Finally the standard and basis for the selection of optimal wavelengths is set up.
