摘　　要：在传统的半解析ＭｏｎｔｅＣａｒｌｏ方法的基础上作了进一步改进，用扭曲的Ｈｅｎｙｅｙ－Ｇｒｅｅｎｓｔｅｉｎ函数（Ｈ－Ｇ函数）来表示散射相位函数，并由Ｈ－Ｇ函数直接得出散射角θ的表达式。计算结果表明。The Monte Carlo method is a good way to calculate the received oceanic lidar signals, but its disadvantage is that the calculation efficiency is very low. The traditional semianalytic Monte Carlo method is improved in this paper, which includes a distorted Henyey Greenstein function used to approximate the scattering phase function, and the expression of the scattering angle θ obtained from H G function. The calculations from the received oceanic lidar signals are in good agreement with experiments.
