Subject field(s)
  • Magnetism and Electromagnetism
  • Special Water Transport
  • Physical Geography (General)
CONT

Submarines are vulnerable to detection through their underwater magnetic signature. As this influence is unrelated to acoustic signatures, magnetic detection is feasible even for acoustically-quiet submarines or in littoral waters. The MAD hardware and the associated geological noise-reduction algorithms and submarine-detection algorithms are used to localize submarines from aircraft. The MAD technology has significant links to the geophysical exploration industry.

  • Géographie physique (Généralités)
CONT

Les sous-marins sont vulnérables à la détection en raison de leur signature magnétique sous-marine. Comme cette influence n'est pas reliée aux signatures acoustiques, la détection magnétique est possible même pour des sous-marins à acoustique atténuée ou dans les eaux littorales. Le matériel MAD et les algorithmes géologiques réducteurs de bruit et les algorithmes de détection des sous-marins connexes sont utilisés pour localiser les sous-marins à partir d'un aéronef. La technologie MAD est étroitement liée à l'industrie de la prospection géophysique.

Key term(s)
  • détection d'anomalie magnétique
