A discrete volume scattering model based on a distorted Born approximation was validated with the experimental data from a multi-frequency scatterometer. The influence of the ground interface has been found important for high wavelength bands while as for bands with low wavelength, the soil contribution is negligible under vegetated conditions. It could be concluded both from the experimental and simulation results that low frequency radars (L-band) are most suitable for soil moisture determination and the soil moisture determination gets difficult with the high frequency radars (X-band) which are suitable for wheat growth monitoring
