Abstract

The future spatial SWOT mission will use a new altimetric sensor "KaRIn", which is a Ka-band interferometric SAR system operating on near-nadir swaths on both sides of the satellite track [1]. The objective is to study the height of the earth's water surfaces, mainly oceans, but also continental water surfaces such as lakes and rivers. This article dedicated to water surface detection methods, presents a multi-scale line extraction approach that has been adapted to the specificities of the KaRIn instrument, and gives some preliminary results obtained on simulated SAR images.
