The ONERA RAMSES system (Radar Aéroporté Multi-spectral d'Etude des Signatures) is a flexible SAR system in constant evolution developed mainly as a test bench for new technologies and to provide specific data for TDRI (Target Detection, Recognition and Identification) algorithm evaluation. It is flown on a Transall C160 platform operated by the CEV (Centre d'Essais en Vol). Recently a POL-INSAR mode has been added where the system is able to acquire simultaneous interferometric polarimetric data in X band. This paper relates the preliminary analysis of data acquired over an agricultural test site around Avignon in Southern France. The polarimetry associated with interferometry provides the necessary elements for understanding the different scattering mechanisms. Several areas display a significant difference in elevation as a function of polarimetry. This is due to the presence inside the resolution cell of multiple responses associated with different scattering elements. These preliminary observations have shown the potential of X band POLINSAR. This is of particular interest now with the prospect of a new X band fully polarimetric radar in space (Terra-SAR X band).
