Lidar multiple scattering return from clouds was simulated by means of semianalytic Monte Carlo method in order to obtain atmosphere extinction and backscattering coefficeint exactly.The influence of the receiver field of view and medium optical depth on multiple scattering was discussed.The relation between cirrus/water clouds of multiple scattering factor and optical depth was studied.The results show that the presence of the multiple scattering can lead to an underestimation of the extinction coefficient and has little influence on backscattering coefficient.
