Cerberus Diver Detection Sonar (Mod 2)

The Cerberus DDS system can detect open circuit divers, closed circuit divers, and underwater vehicles (e.g. swimmer delivery vehicles) with a high rate of accuracy. It has the ability to differentiate divers from marine life and other contacts. It can process thousands of contacts on each ping. The Cerberus system is available in two variants; configured for shipboard deployment or as a fixed system for port and harbour protection. The portfolio includes a range of optional equipment that enables the user to configure their installation appropriately. The system has a 360° coverage with an area detection of up to 4.5km² dependent on the acoustic environment. The GUI can display 50 tracks simultaneously and, once a threat has been identified, raise an audible and visual alarm to allow the user to take precautionary action.
