Abstract
A physical and mathematical model of the echo signal reflected from cloud-rain systems is presented and substantiated. Algorithms for obtaining unbiased, efficient and consistent estimates of the first and second initial moments of the echo signal from the rain are proposed. Schemes of estimation of physical parameters of raindrops on the basis of estimation of power of the reflected signal: induced dipole moment of a raindrop, attenuation at propagation of a signal along a spherical coordinate of range there and back and parameters of cloudy-rain system: intensity of a rain, water content of cloudy-rain system are offered. The connection of induced dipole moment of a raindrop with the estimation of dielectric permittivity and conductivity of raindrops is shown.
