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
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
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.
