Acoustic thermometry — of Ocean Climate (ATOC) is an idea to observe the state of the world s oceans, and the ocean climate in particular, using long range acoustic transmissions. Prototype measurements of temperature have been made in the North Pacific Basin and… … Wikipedia
Acoustic network — An acoustic network is a method of positioning equipment using sound waves. It is primarily used in water, and can be as small or as large as required by the users specifications.The simplest acoustic network consists of one measurement resulting … Wikipedia
Acoustic Doppler Current Profiler — Head of an ADCP with the four transducers ADCP view ahead, mo … Wikipedia
Superheterodyne receiver — A 5 tube superheterodyne receiver made in Japan around 1955 In electronics, a superheterodyne receiver (sometimes shortened to superhet) uses frequency mixing or heterodyning to convert a received signal to a fixed intermediate frequency, which… … Wikipedia
Underwater acoustic communication — is a technique of sending and receiving message below water. There are several ways of doing such communication but the most common is using hydrophones. Under water communication is difficult due to factors like multi path propagation, time… … Wikipedia
Ocean acoustic tomography — The western North Atlantic showing the locations of two experiments that employed ocean acoustic tomography. AMODE, the Acoustic Mid Ocean Dynamics Experiment (1990 1), was designed to study ocean dynamics in an area away from the Gulf Stream,… … Wikipedia
Electro Magnetic Acoustic Transducer — An Electro Magnetic Acoustic Transducer (EMAT), is a non contact inspection device that generates an ultrasonic pulse in the part or sample inspected, instead of the transducer. The waves reflected by the sample induce a varying electric current… … Wikipedia
Horn (acoustic) — A horn is a tapered sound guide designed to provide an acoustic impedance match between a sound source and free air. This has the effect of maximising the efficiency with which sound waves from the particular source are transferred to the air.… … Wikipedia
Multilateration — is a navigation technique based on the measurement of the difference in distance to two or more stations at known locations that broadcast signals at known times. Unlike measurements of absolute distance or angle, measuring the difference in… … Wikipedia
Geophysical MASINT — is a branch of Measurement and Signature Intelligence (MASINT) that involves phenomena transmitted through the earth (ground, water, atmosphere) and manmade structures including emitted or reflected sounds, pressure waves, vibrations, and… … Wikipedia
SOFAR channel — The SOFAR channel (short for Sound Frequency and Ranging channel), or deep sound channel (DSC),[1] is a horizontal layer of water in the ocean at which depth the speed of sound is minimal. The SOFAR channel acts as a waveguide for sound, and low… … Wikipedia
