Abstract：In recent years, three famous models have been frequently mentioned in soil moisture inversion, which are Oh model, Dubois model and Shi model. This paper deals with the correlation between radar backscattering coefficient and soil moisture based on the Shi model, and studies the relationship between radar backscattering coefficient, incidence angle and surface soil moisture on the basis of inversion.
