Abstract

The Synthetic Aperture Radar (SAR) imaging technique enables the mapping of the Earth’s surface independent of weather and light conditions, which makes it a suitable instrument during Antarctic winters. Since the early 1990s, imaging radar techniques have been established in polar sciences. The imagery can be used to support Antarctic wintering staff; e.g. to detect crevasses or other surface features. To do so, the radar backscattering behaviour of homogeneous (undisturbed) and heterogeneous (crevassed) areas is used to map crevasse fields or ice edges. A semi‐automatic technique of surface feature detection can help to process the data more rapidly. Nevertheless, an experienced observer is crucial in emergency cases.
