Iceberg Detection Using Compact Polarimetric Synthetic Aperture Radar [PDF]

open access: yesAtmosphere-Ocean, 2012
In recent years, the use of synthetic aperture radar (SAR) for iceberg detection has been increasing thanks to the greater availability and coverage of SAR data, particularly polarimetric data. Greater amounts of polarimetric information can increase detection performance, preventing false alarms and missed detections.

Iceberg Detection using Satellite Images

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2021
Chunks of ice present genuine risks for transport route and seaward establishments. Subsequently, there is a huge interest to limit them ideal and over tremendous regions. As a result of their autonomy of overcast cover and sunlight, satellite Synthetic Aperture Radar (SAR) pictures are among the favoured information hotspots for functional ice ...

Capturing the crack process of the Antarctic A74 iceberg with Sentinel-1 based offset tracking and radar interferometry techniques

open access: yesInternational Journal of Digital Earth, 2022
In this paper, the crack process of the A74 iceberg is carefully monitored in different aspects by using synthetic aperture radar (SAR) images. First, a offset tracking strategy is designed to retrieve the temporal evolution of the glacier velocity field.

NAVIGATION ASSISTANCE FOR ICE-INFESTED WATERS THROUGH AUTOMATIC ICEBERG DETECTION AND ICE CLASSIFICATION BASED ON TERRASAR-X IMAGERY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Most icebergs present in northern latitudes originate from western Greenland glaciers, from where they drift into Baffin Bay, circulating north along Greenland coast and south along Canadian coast.
