Abstract :
In the work we analyzed the differential reflectivity of polydisperse medium with spherical drops at different wavelengths and found ways to ensure uniqueness of solution of the inverse problem to restore the rain intensity using double-frequency sensing. The results of calculations are performed at wavelengths 0.8 cm, 3.2 cm, 5.5 cm, 7 cm, 10 cm and 35 cm, in addition, we get the system of inequalities that provides an unambiguous measurement of the intensity of precipitation.
