RÉSUMÉ

Development of radar methods for measurements of liquid precipitation parameters is quite important for study of physical processes in the atmosphere and solution of many practical tasks. For this purpose, the dual-frequency sensing is of great interest. However most of published papers concern the analysis of drops with spherical shape, except that the shape of real drops significantly differs from spherical especially for large drops. This fact essentially influences on the characteristics of reflected signals, therefore solution of diffraction problem about field scattering by dielectric particles of ellipsoidal shape is quite actual task. The paper is devoted to the peculiarities analysis of dual-frequency sensing of water drops with ellipsoidal shape by numerical simulation. Consideration is performed in the framework of the Pruppacher model using method of dipole moments for calculations of water drop reflectivity. It is established that differential reflectivity of ellipsoidal drops and drops of spherical shape with the same root-mean-cube radius practically do not differ from each other. Comparison with published data was performed and it showed that results coincide with graphical accuracy for water drops of root-mean-cube radius not more than 3 mm. Weak influence of drop shape on results of dual-frequency sensing was concluded.
