Abstract
A moving ship produces a set of waves in a characteristic linear "V" pattern. This pattern, or some of its components, can often be detected in ocean imagery produced by satellite-borne Synthetic Aperture Radar (SAR) sensors operating at L-band. Some wake components, notably the turbulent wake, may extend for 5-15 km behind the ship. As ship wake detection can provide information such as ship direction and speed, the detection of these wakes can play an important role in satellite surveillance of shipping. Described is research done on the use of the Radon transform to automatically detect ship wakes in Seasat ocean imagery. The objective of the research was twofold: to automatically detect ship wakes and to differentiate ship wakes from other linear ocean features produced by the underwater topography and existing sea conditions. An ADA (Automatic Detection Algorithm) based on the Radon transform was developed and applied to the Seasat imagery. TRUNCATED
