Analysis of the azimutal distribution on the plane of registration of the polarization characteristics of the lidar return from the droplet clouds

The propagation of optical radiation in optically dense media is accompanied by multiple light scattering, which leads not only to the extinction, but also to its depolarization. The method of polarization laser sensing allows to increase the information content of lidar data. The results of numerical simulation of the distribution in the registration plane of the polarization characteristics of a lidar return due to double scattering from droplet clouds are presented in this paper. The influence of the parameters of the particle size distribution of the droplet cloud on the azimuthal intensity distribution of the lidar return with a change in the polarization state of the probe radiation is discussed.
