Abstract

This paper reports preliminary results of a study using L-band SAR imagery to estimate soil moisture and surface roughness for bare fields in a mountain watershed. The small perturbation model requires that the surface roughness profile deviates only slightly from that of a smooth surface. This condition is seldom met by most natural surfaces. Thus, the classic treatment of the scattering model has only limited usage. In this study, we show a simplified model derived from the integral equation model for estimation of soil moisture and surface roughness. We then test this model using JPL L-band AIRSAR data.
