Numerical results of Monte Carlo code in lidar returns considering polarization of light and different phase functions

摘要

Monte Carlo m ethod (MCM) is a useful tool to simulate and understand random process in the nature. Many of this process are difficult to solve by means of a nalytic expressions, due we do not know many of its variables involved in the process. The core of MCM is to generate random variables, which repres ent physical variables, through of its p robability d istribution f unction (PDF). Ev ery random physical variab le has a law of probability to obtain a certain value, within a specific interval. Specially, in the data obtained by l idar returns, we got information of the type of scatterer from the radiation backscatter to receiver. This portion of backscatter radiati on is a little part of the function that describes the total scattering in radians. This function is called " phase function " and has a particular way depending on size, refractive index, shape, etc. of the scatterer. In this work we present the numeric al results to consider different phase functions in the simulation of l idar returns, through of MCM.
