SAR-based techniques to extract bathymetric features
Résumé
This paper presents a survey of Synthetic Aperture Radar-based techniques that are used to extract bathymetric features or create bathymetric maps. With standard techniques, realization of a bathymetric map is currently very expensive. Indeed, the best results are achieved by onboard multi-beam sonars but measurement campaigns are very expensive and time-consuming especially for large coverage or remote areas. SAR-based imaging methods can help to reduce the costs and improve the coverage of bathymetric data. To achieve the needs of the marine renewable energy sector, two main approaches to perform the extraction of bathymetric information exist: current-based method and wave-based method. For each of them, we will discuss their applicability and their quality.
