Technical Abstract: In this study, we computed the Radar Vegetation Index (RVI) using observations made with a ground based multi-frequency polarimetric scatterometer system over an entire wheat growth period. The temporal variations of the backscattering coefficients for L-, C-, and X-band, RVI, vegetation water content (VWC), and fresh weight were analyzed. We found that the L-band RVI was very sensitive to VWC and fresh weight. Based on the correlation analysis between RVI and these growth parameters, we developed equations for the estimation of VWC and fresh weight.
