An improved Two Scale Model (TSM) has been investigated for the depolarization of electromagnetic waves from bare soil surfaces. Classical TSM produces depolarized results due to the tilt of reflecting plane. To include the contribution of actual phenomenon, we add the second order scattering effects at small scale and develop an improved TSM. The performance of the new TSM is assessed by comparing the simulation results in backscattering configuration with the measured data, Advanced Integral Equation Model and Second order Small Slope Approximation at L-, S-, C- and X-band frequencies for a variety of roughness conditions. Finally, we use the new TSM to predict the bistatic scattering and compare the results with classical TSM.
