In Exposure Guidelines for Navy Divers Exposed to Low-Frequency
Active Sonar, a 1996 report by F.
Problem is, the Low Frequency
Active Sonar (LFAS) will do nothing to protect us but might well deafen and disorient much of the ocean's sea life [Summer '99 EIJ].

The app uses a "short-range
active sonar system" to detect respiration in a person within the distance of about 3 feet.
Scheduling algorithms are applied to ship data from US Navy ranges and to
active sonar arrays.
He was seconded to and then worked for the Admiralty Research Establishment to develop and deploy bistatic
active sonar systems for the investigation and modelling of the thermal layers and channels in the world's oceans.
In the 1990s, Chia acquired Russian Kilo-class submarines with anechoic coatings that reduced vulnerability to
active sonar detection and battery technology that increased underwater speed and endurance.
The other notorious producer of acute AONP is
active sonar from
Tom Avsic, a hydro-acoustics engineer at ThyssenKrupp, spoke about how
active sonar helps to detect submarines that give off less radiated acoustic noise.
Under this general background, in this paper, we conduct the research on the reverberation scattering characteristics for
active sonar echo detection system.
