Dans le cadre de cette etude, nous avons utilise des images de RADARSAT-1 et de RADARSAT-2 ScanSAR
Wide afin de reperer les cretes manuellement dans un couloir de navigation hivernal du detroit d'Hudson pour la periode allant de 1997 a 2012.
Similar to conventional ScanSAR
, the antenna elevation beam is periodically switched from subswath to subswath to achieve wide swath coverage illumination.

SAR images with 30 m and 100 m pixel resolution, respectively from ERS-2 and RADARSAT ScanSAR
(Canadian Space Agency), were acquired through a data acquisition request processed by the ASF.
A total of 1,227 RADARSAT-2 ScanSAR
Narrow A images (C-Band, VV polarization, 300 km by 300 km) were provided to the SOIN team by MetOc Halifax.
While obtaining large imaging swath, ScanSAR
mode  is proposed in which the antenna directivity is fixed, swapping between different strips.
For this study, ScanSAR
wide data were used for their high temporal and broad spatial coverage.
An effective solution for wide-swath imaging is ScanSAR
[3,4], which increases the unambiguous swath width at the cost of an impaired resolution, whereas spotlight mode [5,6] can provide high resolution but with a limited coverage.
Most were obtained in the ScanSAR
mode, with swath widths of 500 km and resolutions of 100 x 100 m, although special investigations (e.g., Budkewitsch et al., 1999) have yielded a modest number of higher-resolution scenes, particularly for the Expedition Fiord area and for the Wolf Fiord area in southern AHI.
