AN/AQS-13 dipping sonar deployed from an SH-3 Sea King. The AN/AQS-13 series was a helicopter dipping sonar system for the United States Navy.These systems were deployed as the primary inner zone anti-submarine warfare (ASW) sensor on aircraft carrier based helicopters for over five decades. [1]
Passive sonar systems may have large sonic databases, but the sonar operator usually finally classifies the signals manually. A computer system frequently uses these databases to identify classes of ships, actions (i.e. the speed of a ship, or the type of weapon released and the most effective countermeasures to employ), and even particular ships.
HELRAS or the Helicopter Long Range Active Sonar is a naval helicopter undersea sensor, a dipping sonar (a form of towed array sonar), deployed by helicopters of many naval air forces around the world to detect submarines; it is a form of geophysical MASINT.
Thomson Marconi Sonar or TMS was formed in 1996 by the merger of the sonar systems businesses of French defence electronics specialist Thomson-CSF and British company GEC-Marconi after the payment of a balance by the latter.

SURTASS Twin-Line consists of either the long passive SURTASS array or the Twin-line array, consisting of two shorter passive arrays towed side by side.
Multibeam sonar is used to map the ocean floor A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.
The first commercial side-scan system was the Kelvin Hughes "Transit Sonar", a converted echo-sounder with a single-channel, pole-mounted, fan-beam transducer introduced around 1960. In 1963 Dr. Harold Edgerton, Edward Curley, and John Yules used a conical-beam 12 kHz side-scan sonar to find the sunken Vineyard Lightship in Buzzards Bay ...
