After successful tests with a U.S. submarine using a test array at Eleuthera the Navy ordered six LOFAR systems for installation. The shore stations where the operational array and cable, composing a surveillance sonar set, terminated, were given the generic and non revealing term Naval Facilitity (NAVFAC).
The type designation "UQC" stands for General Utility (multi use), Sonar and Underwater Sound and Communications (Receiving/Transmitting, two way). The "W" in WQC stands for Water Surface and Underwater combined. The underwater telephone is used on all crewed submersibles and many Naval surface ships in operation.
AN/SQS-53 is an improved version of AN/SQS-26CX. The main difference between the SQS-26CX and SQS-53 sonars is the digital computer interface with the Mk 116 anti-submarine warfare (ASW) weapon control system in the latter. [4] In addition, AN/SQS-53 sonar can be fitted with the Kingfisher small obstacle (mines) avoidance sonar. [4 ...
"Sonar" can refer to one of two types of technology: passive sonar means listening for the sound made by vessels; active sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. [ 4 ]
The French entity, Thomson Sintra, brought in by Thomson-CSF, was the European leader in defence-related sonar systems and the world's second after Lockheed Martin Loral, with annual sales of 1.5 billion francs, split between submarine sonars (35%), anti-submarine warfare systems (27%), airborne sonars (18%) and mine warfare (15%).
USHUS is a multipurpose integrated sonar suite used for detecting and tracking enemy submarines, surface vessels, and torpedoes as well as for underwater communication and obstacles avoidance operations. The sonar capabilities of includes active and passive sonar surveillance, underwater communication and is capable of interception and.
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. [1] Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting ...
Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies.
