An algorithm for soil moisture change estimation is proposed by using S-band (3.0GHz) and VV polarization simulated backscattering-data based on IEM model. Such typical parameters as soil moisture, surface roughness and incidence angle are chosen to simulate two radar images for validation and improvement of the algorithm. The comparison results are well consistent with the inputting parameters under the applicable condition, which shows that the method can estimate spatial and temporal change of soil moisture.
