Rice Backscattering Simulation, Verification and Parameter Sensitivity Analysis

This paper establishes rice microwave scattering model according to the Monte Carlo method, and modifies the model to meet the rice growth characteristics. The model simulation results were compared with scatterometer measured data, the result show that the proposed rice backscatter model can well simulate the backscattering characteristics of rice. The variation ranges of input parameters of the model were set according to the actual growth parameters of rice. The rice backscattering coefficients with different input parameters, such as rice straw and rice leaf parameter, were simulated. Finally, the sensitivity analysis according to the rice backscattering coefficient and growth parameters is presented.
