“…Rain is an important and recurrent phenomenon in meteorology which has a serious effect on the communication links, especially the earth-space link. Many papers had researched the rain attenuation and depolarization that are proportional to rain rate [7] [8] . At L-band, the rain attenuation can be neglected, for the reason that although the rain rate is 150 mm h −1 , it's still less than 0.1dB km −1 [9] .But, the raininduced depolarization across the earth-space rain path is strongly connected with rain rate.…”

Abstract-In recent years, the Atmosphere-Ocean and Space environmental remote sensing technology such as atmospheric temperature and moisture profiles, sea surface wind field, and total electron content based on the GNSS signals has been widely concerned. This paper researches the mechanism and method of the retrieval of rain rate based on the depolarization of GNSS signals. According to a non-spherical raindrops model and raindrop size distribution, the function relation between the cross-polarization discrimination XPD defined to describe the depolarization and rain rate is established based on the non-spherical particle scattering algorithm. The feasibility of retrieving rain rate using the XPD is simulated and analyzed. The new technology of real-time, continuous, global detection of rain rate explored in this paper is of great significance to the expansion of the application of GNSS signals in the field of remote sensing of the atmosphere-ocean environment.

“…The essential parameter is the differential propagation constant which is obtained from the single particle scattering coefficients by the method of van de Hulst [1957]. A number of measurements of cross polarization (from linear vertical or linear horizontal) including both terrestrial and satellite observations have been reported [Watson and Arbabi, 1973a;Semplak, 1974a;Shimba et al, 1974;Taur, 1975;Bostian et al, 1975;Gray, 1975]. In order to derive an engineering estimate of cross polarization from the scattering theory of a single raindrop, it is necessary to supplement the van de Hulst method by assigning values to, or assessing the significance of, a number of factors.…”
