Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1 (AMM) to classify the coastline of Antarctica in terms of surface structure patterns close to the(More)
Icebergs represent hazards to maritime traffic and offshore operations. Satellite Synthetic Aperture Radar (SAR) is very valuable for the observation of polar regions and extensive work was already carried out on detection and tracking of large icebergs. However, the identification of small icebergs is still challenging especially when these are embedded in(More)
Multi-polarization synthetic aperture radar (SAR) systems are in particular useful for identification and separation of different scattering mechanisms and their sources in a medium (Oliver & Quegan, 1998, p. 319). The Canadian RADARSAT-2 (RS-2) carries a fullypolarimetric SAR system which measures intensities at VV, HH, HV and VH-polarizations as well as(More)
Icebergs are hazards to lives and goods during navigation in cold waters. In the context of iceberg detection with SAR images, an extensive work was carried out for the detection of large icebergs, but the identification of small bergs or target embedded in sea ice is till difficult. In this work, a new detector is propose to tackle this issue based on(More)
