RESON successful in demonstration of contraband and diver detection systems in 4 UK portsThree separate demonstrations at Southampton, Falmouth and Chichester were conducted to test contraband detection using the SeaBat 7128 multibeam sonar system. These demos were staged in front of representatives from the Royal Navy, the Royal Netherlands Navy, and the US Navy.

During the demonstrations RESON was able to positively identify items as small as a brick at ranges above 30 meters, and at water depths of 7 to 20 meters. For items this small and with detection ranges like this, such has not been achieved by even a modern naval mine-hunter.

A fourth trial for the Royal Navy of the SeaBat 7112 multibeam sonar system was focusing on diver detection. Using the SeaBat 7112 system in conjunction with the SeaBat 7128 system for diver detection, RESON was able to detect targets on a long distance, and making positive distinctions between divers and other targets.

The SeaBat 7128 multibeam forward looking sonar has high resolution and installation flexibility, and is ideal for a variety of underwater imaging applications from a surface vessels, ROV or AUV platforms, in water up to 6000m deep. The focused beams, high ping rate and bandwidth of the SeaBat 7128 combine to provide the user with superior resolution and imaging quality.

SeaBat 7112 multibeam sonar system for diver detection consists of a circular array and projector ensonifying a cylindrical volume of water up to 1000 meters range. Designed to detect small targets such as divers with closed circuit re-breather equipment, the systems will track and alert operators of their presence on a geo-referenced map of the area.
