Ship detection and tracking
Satellite borne SAR instruments data provide an efficient way of detecting ships in the open sea and measuring, through wake and Doppler displacement, their speed and direction. Repeated observation can contribute to a maritime surveillance system, complementing information on routes from coastal radars and shipboard Automatic Identification Systems (AIS).
Particularly COSMO-SkyMed constellation significantly improves the role of SAR in this application because of its high revisit frequency. High spatial resolution observing modes provide ship characterization / classification.
