We have simulated backscatter signals of spaceborne lidar systems with the help of a Monte Carlo model. Calculations were performed for various combinations of system parameters. As typical examples of atmospheric observation targets, two kinds of cirrus cloud and two kinds of aerosol were considered. Both total multiple scattering and the significance of individual higher scattering orders are discussed. For all cases, an approximate multiple scattering factor F was calculated that can be used to correct the single-scattering lidar equation to account also for multiple scattering.
我们借助蒙特卡罗模型模拟了星载激光雷达系统的后向散射信号。针对系统参数的各种组合进行了计算。作为大气观测目标的典型示例，考虑了两种卷云和两种气溶胶。讨论了总多次散射以及各个高阶散射的重要性。对于所有情况，计算了一个近似的多次散射因子F，可用于校正单散射激光雷达方程以计入多次散射。
