Popis:	The principal instrument of the wide-swath altimetry mission SWOT is KaRIn, a Ka-band interferometric SAR system operating on near-nadir swaths on both sides of the satellite track. Due to the short wavelength and particular observation geometry, there are very limited reports on the backscattering from natural surfaces. Models and simulators that cover radiometric and geometric aspects have therefore been developed. This article describes airborne acquisitions and ground measurements that are used to validate the models and simulators, and shows some preliminary results.
