Abstract

Abstract:

To verify the feasibility of using GPS-R technology to inverse vegetation biomass,the principle and method inversing vegetation biomass using GPS reflected signal were introduced.The paper performed an experiment to calculate the signal reflectivity using ICF. Using the relationship between the reflectance signal and vegetation biomass,the vegetation biomass was figured out and compared with the result of NDVI remote sensing.The results indicate that it is feasible to retrieve vegetation biomass using GPS-R remote sensing,which has great significance in vegetation plant and carbon emission investigation.

Key words: GPS-R, vegetation biomass, reflected signal, reflectivity, ICF
