Imaging Sonar Systems

Imaging sonar is a high-frequency, narrow field of view, underwater sonar that produces video-like acoustic imagery that can detect and identify submerged objects of interest, even in low-to-no visibility conditions. Imaging sonar systems are used by responders to inspect ship hulls and  pier and bridge pilings, direct divers to objects of interest, track divers underwater, and search for underwater obstructions ahead of vessels.
