TL;DR: The rationale of this paper is to assume that SWOT's scientific requirements are met on all errors but the ones being cross-calibrated, and they are able to deal with higher error levels (e.g., if hardware constraints are relaxed and replaced by additional ground processing).

TL;DR: The measurement principle, the processing steps and the specificities of the interferometric SAR data of KaRIn as compared to conventional spaceborne SAR systems are described.

TL;DR: A multi-scale line extraction approach that has been adapted to the specificities of the KaRIn instrument is presented, and some preliminary results obtained on simulated SAR images are given.

TL;DR: Evaluating the errors of the extracted water levels in different hydrodynamic and topographic contexts in the Seine estuary based on simulated SWOT HR data confirms height errors generally below 10 cm after km-scale averaging for the majority of the observations.

TL;DR: In this paper, a linear structure detector is used to produce a map of likely line structures and then a limited number of nodes along the prior river centerline are extracted from the exogenous database and used to reconstruct the full river centreline from the detection map.
