A comparative estimate is presented of the high-intensity radiation reflected from cloud crystals of different shape. Ensembles of ice plates are chosen in model investigation of crystal clouds containing oriented particles. The expressions obtained for scattering coefficients in the frameworks of physical optics make it possible to study angular distribution of the intensity of scattered radiation as well as its polarization properties. Also, the advantages of bistatic laser sounding over the monostatic one are mentioned. It is shown that one can determine the size spectrum of plates and the plate flatter in atmospheric formation of inhomogeneous composition from variations of absolute and relative values of the scattering coefficient obtained at near-forward scanning by moving the source. In addition, one can estimate the refractive index and orientation of particles in space from the data on polarization characteristics of scattered radiation.
