AN/WQX-2

The AN/WQX-2 is a diver detection sonar used in defense against swimmer incursions. It is in service with the US Navy. It uses Kongsberg Mesotech components. It can detect divers up to 2400 feet away.

The AN/WQX-2 finds range and bearing of the detected target relative to the sonar. The C3D console developed by SPAWAR converts this to a GPS position. It has software to distinguish diver echoes from shoals of fish, marine mammals, debris, bubbles from boat wakes, etc.
