Iceberg detection using COSMO-SkyMed satellite constellation images

摘要

The new constellation of COSMO -SkyMed (CSK) satellites, which carry on board a SAR-X instrument, offers a unique opportunity for the study of sea ice distribution in polar regions and for the detection of drifting icebergs. To exploit this new class of SAR images, a specific processing scheme, consisting of 4 sequential blocks, was developed. The 4 blocks perform: i) ingestion of the raw image into a commercial software for precise geo-location; ii) extraction from the full scene of image subsets containing iceberg infested areas; iii) speckle filtering; iv) segmentation by different algorithms taken from a "free and open source software" (FOSS) library. The results of the application of this processing scheme to a CSK image of Antarctica containing icebergs are presented and discussed.
