SETHI and RAMSES-NG flexible multi-spectral airborne remote sensing research platforms

SEHI and RAMSES-NG are airborne SAR systems developed by the French Aerospace Lab. ONERA, and integrating various sensors. The microwave ones cover from VHF-UHF to X Band, full polarimetric and very high resolution, along track and cross track interferometry and very high precision multi-baseline capacity for interferometry and tomography applications. The optronic sensors offer very high spatial resolution visible images and fine spectral scene analysis in VNIR and SWIR bands. This paper presents the flexible capacity of these platforms and last campaign results with various sensor configurations.
