In this paper we present some results of a comparison made between the backscattering phase matrices of crystal clouds measured experimentally with the polarization lidar "Stratosfera 1M" and calculated using model polydisperse ensembles of partially oriented ice cylinders. The comparison shows that the model used describes the main experimental facts quite satisfactorily. Thus, in particular, the results on the direction of preferred orientation of particles and on the degree of their orientation calculated using the model well agree with those reconstructed from the experimental lidar data.
