Analysis of characteristics of light propagation through clouds and Monte Carlo simulation

In order to study the multiple scattering characteristics of light propagation through clouds,received power was analyzed,the laser transferring process in clouds was simulated with Monte Carlo method,and the waveform broadened temporal signal was obtained.Results illustrate the broadened signal has a steep rise edge followed by an exponential tail,and that the broadened shape is affected by some parameters such as asymmetry factor,clouds thickness,extinction coefficients,receiver field of view,especially strongly by asymmetry factor and clouds thickness.
