Abstract :
Presents an investigation of the characteristics of multiply-scattered lidar returns from homogeneous layers of monodispersed nonspherical particles. A Monte Carlo procedure has been employed to simulate lidar measurements. Total detected power as well as depolarization of the detected signal have been calculated for a variety of particle deformations and orientations, fields of view (FOVs) of the receiver and optical thicknesses of the medium. It has been found that in certain cases multiply-scattered photons cause a decrease in the depolarization of the received light. The results have been checked, for double scattering, by comparing them with the outcome of analytical calculations
