Theoretical study on GNSS-R vegetation biomass

GNSS-R(Global Navigation Satellite System-Reflectometry) remote sensing has been attracted much more attention during the past decade. As for land scenario, soil moisture and vegetation properties are the research priorities. This paper focuses on the initial study of GNSSR vegetation biomass using the already developed microwave scattering model Bi-mimics (Bistatic-Michigan Microwave Canopy Scattering). After some modifications, forest and crop specular simulations indicate that as for GNSS-R configuration, vegetation biomass monitoring is feasible, RL and RV polarization scattering properties are influenced by vegetation types, scattering angles and polarizations. It is a complex process and theoretical simulations provide some suggestions for GNSS-R vegetation remote sensing.
