Anti-Submarine Warfare Fiber-Optic Passive Sonar
The U.S. Navy and Northrop Grumman continue to be actively involved in the development of all fiber-optic acoustic sensor arrays for Anti Submarine Warfare passive sonar. Depending on the application, these arrays may contain optical geophones, fiber-optic hydrophones, and/or fiber-optic microphones. They may be deployed in all types of terrain and marine environments to accommodate such applications as perimeter security, harbor monitoring, and ground surveillance. Programs include flank arrays, towed arrays, and ocean-bottom arrays.
