    • Aegir installation and user manual 

      Hannevik, Tonje Nanette; Olsen, Richard (2014-11-19)
      There have been many civilian Synthetic Aperture Radar (SAR) satellites in orbit. The Norwegian Defence and the Norwegian Coast Guard have used the Canadian SAR satellites RADARSAT-1 and RADARSAT-2 operatively for fisheries ...
    • Evaluation of Radarsat-2 for ship detection 

      Hannevik, Tonje Nanette (2011-12-05)
      Ship detection and monitoring has become one of the first operational services from civilian spaceborne Synthetic Aperture Radar (SAR) satellites. The Norwegian Coast Guard presently uses such data to support fisheries ...
    • Improving ship detection by using polarimetric decompositions 

      Hannevik, Tonje Nanette; Eldhuset, Knut; Olsen, Richard (2015-10-12)
      Norway’s large ocean areas require efficient methods to monitor vessels. Radar satellites in orbit today offer dual- or quad-polarised data, which ease the task of detecting vessels in a SAR (Synthetic Aperture Radar) ...
    • RADARSAT-2 new modes 

      Hannevik, Tonje Nanette (2012-07-10)
      RADARSAT-2 has provided new and better opportunities for spaceborne monitoring of vessel traffic and fishing activities because of better flexibility in choice of resolution, polarisation and look direction. Due to user ...
    • Ship detection using high resolution satellite imagery and space-based AIS 

      Hannevik, Tonje Nanette; Skauen, Andreas N. (2011-12-15)
      Denne rapporten presenterer en test utført i Malangen nær Tromsø i Nord-Norge i september 2010. Høyoppløselige Syntetisk Aperture Radar-bilder (SAR) fra RADARSAT-2 har blitt brukt for å analysere hvordan SAR-bilder og ...
