Abstract: 

Radar methods of investigation of clouds and precipitation are the most effective methods of remote sensing of the atmosphere. The advantages of radar techniques are the abilities to measure quickly the characteristics of precipitation over large areas. In the context of the turbulent medium the particles may be at a different angle relatively to the incident field, so in the paper there was an attempt to study the scattering indicatrix of snow crystals (dependence of the radar cross-section (RCS) on the incidence angle of the electromagnetic wave), which allowed to evaluate the variability of the RCS of snow crystals at the variations of the elevation angle of the radar antenna. For the numerical simulation of the scattering properties of the snow crystals we used two types of particles at various angles of observation, at that in the paper we consider two azimuthal angles of incidence of electromagnetic field in a wide frequency range.
Keywords: scattering indicatrix, snow crystal
