SETHI, the ONERA airborne SAR sensor, and his low frequency capability

SETHI is the airborne SAR system developed by the ONERA, the French Aerospace Lab dedicated to civilian application. This new SAR system was designed to explore the science applications of radar remote sensing; it can operate over a wide range of frequency bands (X, L and UHF/VHF) and it has polarimetric and interferometric capabilities. In this paper, we will more specifically illustrate the low frequency capability of this new airborne SAR system and provide some results obtained with the system.
