SummaryObjective: To obtain a first assessment of the performance of TerraSAR-X for vessel surveillance. Approach: 1. Collect a few TerraSAR-X images over an area where vessel traffic is known. For this, the North Sea off the Netherlands coast is chosen. 2. Collect concurrent data from AIS (Automatic Identification System) and VMS (Vessel Monitoring System). Both systems are capable of giving vessel positions and identifications at the time of imaging AIS of the larger merchant vessels, VMS of fishing vessels longer than 15 m. AIS data will be collected by TNO, using their own AIS receiver installed on their site near the coast. VMS data are available from national authorities; JRC have access to them because they are a part of the European Commission. 3. The TerraSAR-X images will be analysed in three ways: (3.a) Visually by an operator (JRC). (3.b) By JRCs automatic ship detector, which has been developed on C-band imagery. This detector is intended to be a prototype for operational vessel detection and works with a CFAR approach. (3.c) By a more experimental target detector based on an approach using wavelets by UPC. 4. The results of the analysis (vessels detected or not, their position, size, orientation) will be compared with the ground truth data from the AIS and VMS. Data requirements: 3 ScanSAR images, around 45 degrees incidence, HH polarisation, with some time in between to avoid having too similar conditions. Deliverables: A scientific publication giving an assessment of the performance of TerraSAR-Xs ScanSAR mode for vessel detection and classification. The assessment is quantitative (although based on only 3 scenes) and excludes the smallest vessels because they do not carry AIS or VMS. Funding: All parties fund this work from their normal internal research budgets. Note that this is a relatively small study.
