Airborne data collection for SWOT mission

In order to support SWOT and future altimetry space missions at Ka-band, an airborne measurement campaign has been done by ONERA. A large Ka band radar dataset has been recorded and processed, leading to backscattering measurements over different kinds of water surfaces, and with different wind regimes. For the first time at this frequency band and viewing direction close to nadir, an interferogram has been processed. Its shows a good coherence level, particularly over water surfaces which were the objectives of this measurement campaign.
