Processing of proposed KARIN/SWOT data

This article summarizes the data processing of the proposed wide-swath altimetry mission Surface Water and Ocean Topography (SWOT), and more specifically the processing steps up to level 2 for the Ka-band Radar Interferometer (KaRIn), which is a near-nadir viewing bistatic SAR system. A general overview of the proposed processing chains and data products is given, and some particularly challenging processing steps are commented on.
