acoustic warfare
(
DOD,
NATO) Action involving the use of
underwater acoustic energy to
determine,
exploit,
reduce or
prevent hostile use of the underwater acoustic spectrum and actions which retain friendly use of the underwater acoustic
spectrum. There are three divisions within acoustic warfare:
1. acoustic warfare support measures. That aspect of acoustic warfare involving actions to search for,
intercept, locate, record and analyze
radiated acoustic energy in water for purpose of exploiting such radiations. The use of acoustic warfare support measures involves no
intentional underwater acoustic emission and is generally
not detectable by
the enemy.
2. acoustic warfare
countermeasures. That aspect of acoustic warfare involving actions taken to prevent or reduce an enemy's effective use of the underwater acoustic spectrum. Acoustic warfare countermeasures involve intentional underwater acoustic emissions for
deception and
jamming.
3. acoustic warfare
counter-countermeasures. That aspect of acoustic warfare involving actions taken to ensure friendly effective use of the underwater acoustic spectrum despite the enemy's use of underwater acoustic warfare. Acoustic warfare counter-countermeasures involve
anti-acoustic warfare support measures and anti-acoustic warfare countermeasures, and may not involve underwater acoustic emissions.
