The airborne SAR-system: SETHI airborne microwave remote sensing imaging system

SETHI, the airborne SAR system developed by the ONERA, the French Aerospace Lab., integrates a new frequency band radar: the UHF-VHF component. Thanks to its new payload, SETHI can operate over a wide range of frequency bands from UHF-VHF, to X including L-Band and has polarimetric and interferometric capabilities. We describe in this paper the pod-based SAR-system SETHI and its associated numeric remote control. Then we describe the UHF-VHF validation campaign and as a conclusion the first polarimetric SAR results.
