Abstract

The GNSS-R (Global Navigation Satellite System-reflectometry) wetland remote sensing is achieved by receiving a reflected signal. Based on the relationship between reflected energy and permittivity of the reflective medium, the inversion model is built for GNSS-R terrestrial humidity remote sensing, which is the terrestrial humidity dielectric model of the L-band satellite navigation signal left-polarized wave component model on the basis of the analytical expression of vertical polarization. This paper thereby provides theoretical and methodological support for the detection and inversion of GNSS-R soil moisture.
