Optical model of a particle on bistatic polarization laser sensing of crystalline clouds

The large potential opportunities in study of the top and average atmosphere can be realized at remote sensing through a use of the bistatic polarization scanning lidar. In the report, a process of scattering of polarization radiation by crystalline cloud to bistatic technique of sensing is investigated. The translucent plate crystal, as an object of study of scattered radiation on a separate particle is considered. The choice of such model is caused in the report. There are obtained the expressions for scattering cross sections within the physical optics formalism. As a result of the numerical analysis the regular dependences of depolarization ratio and ratios of parameteres of Stokes vector on the orientation angle of plate with respect to the sensing direction, the orientation of the polarization plane, the refractive index of plate have been established. It is arrived the obviously expressed dependence of scattering cross section from plate radii.
