Wide Area Surveillance refers to the continuous monitoring and tracking of the earth's surface, using Synthetic Aperture Radars (SAR) on air and space-borne satellites. The present work is an application of the same for maritime ship detection in the sea. The wake is a rich source of information about the ship's particulars. Current research shows that CFD studies predict ship wakes and thus have a role in the ship detection process. We find that all cases of ship detection can be done with this technique with less than 7% error. The study has been further extended to look at the case of a ship turning. This is the first study to establish with evidence the effect of turning ship wakes on detection and we find it to be applicable to 6% error. Further work is needed to determine the practicality of this approach for the Navy by employing SAR images.
