Research on Crop Biomass Monitoring Using GNSS-R Technique based on Bi-Mimics Model

Wu Xuerui1,2,3,Li Ying1,Li Chuanlong1(1.Institute of Environment Information,Dalian Maritime Universtiy,Dalian 116026,China; 2.Department of Environment Resources and Management;Chifeng College,Chifeng 024000,China; 3.State Key Laboratory of Remote Sensing Science,Jointly Sponsored by Institute of Remote Sensing Applications,Chinese Academy of Sciences,Beijing Normal University Beijing 100875,China)  
GNSS-R(GNSS-Reflectometry) remote sensing is a kind of bistatic radar model.Mimics(Michigan Microwave Canopy Scattering)model is based on first-order radiative transfer equation.It is developed to Bi-Mimics(Bistatic-Mimics)model according to bistatic radar configuration.Bi-Mimics model is adapted to crop bistatic scattering model.In this model,the trunk layer is eliminated and the interactions between the trunk layer and ground layer are canceled.Using this model,numerical simulations about scattering properties at GNSS-R working L-band have been carried out.According to GNSS-R configurations,relationship between specular scattering coefficients and crop biomass is also simulated.And the bistatic radar equation is used to simulate the relationship between crop stem biomass and GNSS-R receiver signals.The simulations indicated that GNSS-R is a kind of technique to monitor crop biomass theoretically,but it needs to be further studied.
