This work focuses on the retrieval of Titan’s dune field characteristics addressing different radar modes. The main
purpose of the proposed work is to exploit a possible synergy between SAR and altimeter acquisitions modes to provide
information about dune field. Cassini has performed 86 Titan flybys in which several observations of dune fields have
been collected in altimetry mode. There are several cases in which SAR and altimeter have been acquired over same
areas covered by dune fields, such as during T28 (SAR) and T30 (altimeter) flybys. Altimetry together with SAR data
have been used to derive the rms slopes of dunes (large scale) over Fensal area, this information has been employed to
calculate SAR incidence angle with respect to dunes. We extracted backscattering coefficients of bright and dark areas
detected in the analyzed SAR image in order to evaluate the angular response of scattering. Through the Geometric
Optics model we retrieve roughness values (small scale rms slope) for both dune bright and dark areas.
