The ONERA airborne multi-frequency SAR imaging systems

RAMSES-NG and SETHI, the airborne SAR systems developed by ONERA, integrate new generation of radar and optronics payloads. They can operate over a wide range of frequency bands from UHF-VHF, to X-band including L band with long range, very high resolution, polarimetric and interferometric capabilities. Collected and processed Data are exploited for various studies in the field of Defence, Security and Remote sensing applications. In this paper, we describe these two SAR Systems and associated digital remote control. In conclusion some typical results are presented.
