|Purpose:||Synthetic Aperture Radar (SAR) satellites are used to scan vast areas of ocean to reliably detect any ships that are there. These wide area scans produce low-resolution images, but high-resolution images are needed to identify illegal activities like unregulated fishing.
A new satellite called SAR-XL has two independent radars—one that takes wide angle, low-resolution images, and another than produces high-resolution ones. This project will develop software and systems to allow both of the satellite's radars to work together to first detect the presence of objects like ships and sea ice, and then zoom in to identify them. These updates to SAR satellite technology will improve maritime surveillance activities by providing accurate, timely information about everything happening in Canada's maritime zones. This work supports important activities, such as monitoring the Artic, identifying ships in distress, maintaining Canadian sovereignty in the North, and protecting the border against illegal, unreported, and unregulated fishing and trafficking.|
