The identification of small icebergs in SAR images is challenging especially when these are embedded in sea ice. In this work, a new detector is proposed based on dual-polarized incoherent SAR images. Small icebergs have a stronger cross polarization accompanied by a higher cross- over co-polarization ratio compared to sea ice in many cases. This is the rational at the base of the detector.
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 sea ice. In this paper, a new detector...
