Abstract
Results of study of double frequency method for measurement of rain intensity using three-parameter gamma distribution of drop sizes are presented. For elimination of measurement ambiguity of distribution parameters using data of double frequency sounding the use of data of contact measurement of connection between rain intensity and gamma distribution parameters was proposed. The results of calculations performed by the Mie theory were presented. They allow to estimate applicability of proposed method for polydisperse medium and to give recommendations for choice of frequency range for double frequency radar.
KEY WORDS: radar cross-section, diffraction, differential reflectivity, rain intensity
