%X This paper analyzes the two scattering models and inversion techniques for bare soil surface, which were proposed by Oh(1992) and Dubois(1995), respectively. A method to validate the parameter inversion results of both two models was developed under the condition that no in-situ measurements were collected. Since Integral Equation Method (IEM) provides the relationship between backscattering coefficient and surface parameters in a rather wide range of roughness and moisture conditions, the modeling method of empirical and theoretical models are deeply analyzed and then combined. AIRSAR data are employed to perform the experiments, and the results show that the proposed method is effective to validate the surface parameters of bare soil which are obtained from the empirical models.
