Project Artemis was an experimental research and development project in the late 1950s to mid 1960s to examine acoustic propagation and signal processing for a low-frequency active sonar system that might be used for ocean surveillance.
Asdic was the British version of sonar developed at the end of World War I based on the work of French physicist Paul Langevin and Russian engineer M. Constantin Chilowsky. . The system was developed as a means to detect and locate submarines by their reflection of sound wa
After the war, the U.S. Navy continued to develop MAD gear as a parallel development with sonar detection technologies. Satellite, near-surface and oceanic data from detectors was used to create the World Digital Magnetic Anomaly Map published by the Commission for the Geological Map of the World (CGMW) in July 2007.
The AN/SQS-504 Diver [1] was an early naval medium-frequency active variable depth sonar [2] (VDS) developed in Canada.. The AN/SQS-504 emerged from a post-Second World War program to improve the detection of submarines between the thermal layers in the Gulf of Saint Lawrence. [3]
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian electrical engineer and inventor who received hundreds of patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death).
SURTASS began as development program in 1973 using the new research vessel Moana Wave. In 1980 SURTASS passed OPEVAL. The new Stalwart-class ocean surveillance ships had the first contract awarded on 26 September 1980 and were similar to the prototype ship, the Moana Wave. Initially the SURTASS system were passive, receiving only sonar systems.
