Abstract:
The Sentinel-6 mission altimeter has a SAR capability. It has been designed to allow for achieving about 300m resolution along track. Corresponding results over oceans, as provided in the official products, have proved to be already very good.
Thanks to the Fully Focus SAR technic (FFSAR) (1), it is possible to reach resolutions as narrow as about 2m. This can be very beneficial to altimetry, in particular over hydrological targets.
We will present results obtained in collaboration with CNES, using FFSAR waveforms to derive the height over the Garonne River.
