Abstract
The article presents the numerical calculations of the scanning lidar signals for the case of monodisperse cloud of hexagonal ice plates and columns of 100 microns. The calculation was performed within the approximation of single scattering. The calculation results shows that the scanning lidar is an effective tool to restore the effective slope angle (flutter) of the particles in a cloud. It is shown that as compared to traditionally measured lidar characteristics: backscatter coefficient, linear depolarization and lidar ratios, the element m44 of the scattering matrix is more informative and requires scanning to a smaller angle, less than 45°.
