摘　　要：在激光雷达探测中,关于多次散射雷达回波的研究,散射相位函数是个非常重要的物理量。本文利用Mie理论的递推公式,对单一粒径介质的散射相位函数进行了计算,计算结果与散射理论中前、后向散射峰值大小随粒子半径的增大而增大相一致。同时,对非单一粒径介质的散射相位函数进行了计算,可用于大气、雾和云等气溶胶多次散射的研究。Scattering phase function is a very important physical parameter in lidar detection of multiple scattering returns. In this paper, scattering phase function of one particle radius is calculated by recursive formula of Mie theory. The result of forward and backward scattering peaks increase when the radius of particle has added according to the theory of scattering. At the same time, scattering phase function of non - one particle radius is calculated by recursive formula of Mie theory, which can use for research on multiple scattering of aerosols such as atmosphere, fog, clouds and so on.
