Vessel Detection System (VDS) @ KSAT (1) Two systems in use today: MEOS (KSPT implementation of FFI algorithm) SUMO (JRC developed, integrated in service chain) VDS is in a demonstration/pilot phase at KSAT: No operational day-to-day use(rs) yet, campaigns and demonstrations within projects so far Data from KSAT used for operational VDS by the Norwegian defence VDS is produced and included as a layer for the oil spill monitoring service users Market development is ongoing, world-wide interest
VDS @ KSAT (2) Two satellite systems in use today: Radarsat-1 Envisat ASAR Future satellite systems: Radarsat-2 (TerraSAR-X) Potential future satellite systems: Cosmo/Skymed Sentinel-1 Radarsat-C

SkipSat Norwegian partners FFI, NPI, Norut IT, Kongsberg Spacetec Development of new and existing algorithms and methods Detection based on coherence and intensity Detection based on superresolution techniques Integration of x-band data (new sensors/satellites) Iceberg and vessel discrimination Tracking of vessels and icebergs (based on coming satellite constellations) Implementation and operationalisation New and improved algorithms integrated in the operational service chain (MEOS system) Validation of operational performance
Icebergs Requirements Detection - dimensions Tracking - Where will it go, and what damage will it do? Current Status: Can detect some icebergs, but not calculate size For wide-swath data Easily detected in far range but not in near range Better detection in calm waters (wind shadow, South of FJL)

Repeat Detection Ice band detected in consecutive scenes in the cross-pol band of AP data 12th August 2006 15th August 2006
Ice object detection, West Greenland Over 500 objects detected
Conclusions Iceberg Detection Possible, but dependent on environmental conditions Limiting factor: spatial resolution Iceberg Tracking Limited by size of icebergs in Barents Sea Worth investigating methods can be applied to ice floes - Possible requirement for ship navigation ice velocity
Coherence method (1) Using the coherence improves the target to sea ratio substantially utilising the SLC data, not the detected products as usual today in most systems
Coherence method (2)
Future SAR systems RADARSAT-2, ALOS, TerraSAR-X, Cosmo-Skymed, Sentinel-1, Radarsat Constellation, Higher resolution Polarimetry Other frequencies Continued development of detection systems needed Increased capabilities come at the expense of reduced swath width Wide area surveillance is often not helped More satellites imply higher revisit frequency But at higher cost Improved revisit increases potential for tracking of vessels/icebergs Improved detection performance can be expected
Use of vessel and iceberg detection Fisheries control Monitor and detect illegal fishing Maritime security Illegal trafficking of people and goods Illegal transhipments Recognised Maritime Picture Maritime navigation Navigation in icy waters Maritime traffic monitoring, VTS, traffic separation lanes
