Double frequency sounding of rain using contact measurements

摘要

Study of double frequency method for measurement of rain intensity is presented for three-parameter gamma distribution of drop sizes. The data of contact measurement of gamma distribution parameters were proposed to avoid the measurement ambiguity of radar sounding. The results of numerical simulation on the base of Mie theory are presented that permits to estimate applicability of the method proposed for polydisperse medium and to form recommendations for frequency range choice of double frequency radar.
