In order to study light's propagation in terms of multiple scattering in complex geometrical or heterogeneous media,especially in atmosphere,semi-analysis Monte Carlo method was used,and relative returned signals of the lidar under different atmospheric conditions and systematic parameters were emulated.Consequently,time-relative returned signal curve was derived.And the influence of field of view(FOV)on the returned signal was discussed in detail.It is concluded that while FOV is very narrow,the curve is nearly as the same of single scattering curve,and that with the augment of FOV,single scattering decreases,multiple scattering enhances.
