Abstract

The propagation of optical radiation in optically dense or distant aerosol formations is accompanied by multiple scattering of light, which leads not only to attenuation of radiation, but also to its depolarization. In the case of polarized laser sounding of such media, a feature of the formed double-scattered radiation flux is the anisotropic distribution of polarization characteristics over the cross section of the beam at the focal plane of the lidar receiver. The results of numerical modeling of the lidar return from droplet aerosol formations in the double scattering approximation are reported. The focus is on analyzing the influence of the size of droplet particles on the ratio of polarization degrees of double scattering lidar return at focal plane of receiver when sounding radiation has a linear and circular polarization state.
