SURVEILLANCE

DIDSON™ works well as a component in a harbor surveillance system. A large low-frequency sonar surveys a large volume of water and alerts the operator to an approaching return that exhibits characteristics of a threat. The operator directs a patrol boat to that location and a DIDSON off the side of the boat is used to identify the target as a diver, delivery vehicle, marine animal, or debris. DIDSON can also be used to monitor an underwater location that needs high security, similar to how video surveillance cameras are used on land.
