AbstractThe capability of the RADARSAT synthetic aperture radar (SAR), in combination with the Ocean Monitoring Workstation (OMW), for automated ship detection has been assessed using in situ ship validation information collected during field experiments conducted in 1996 and 1997. Our analysis indicates a 97% ship detection rate for the single beam modes best suited to ship detection (i.e. those beam modes having the largest incidence angles), and an 84% ship detection rate overall across the available set of validation data. Due to limitations in the validation data, the false alarm rate has not been explicitly addressed, aside from keeping it low by adjusting the OMW ship detection algorithm parameters. The validated ships tended to be large in size, 120m in length on average. Our results indicate reliable automated ship detection performance using the RADARSAT/OMW combination, in particular for the recommended ship detection beam modes.
