The main aim of this paper is the investigation of the potential of different radar frequencies for surface parameters estimation. Two case studies have been analyzed. The first is devoted to obtain soil moisture and roughness of bare soils from a combination of X, C and L band SAR images acquired during the SIRC/XSAR mission. The results indicate that the combination of the three bands is particularly useful when roughness parameter estimation is performed. Also the use of the cross-polarization VH has been exploited. The second case study is focused on vegetation water content estimates by using a combination of C and L band data acquired during the SMEX'02 experiment on densely vegetated fields. The errors on estimates are reduced when both C and L band data and a correction for roughness are used.
