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.
