Subject field(s)

  • Surveillance, Detection and Reconnaissance (Military)
DEF

A passive acoustic system for the detection and localization of small-arms fire at long ranges.

OBS

The system is composed of a three-dimensional microphone array mounted on the rear of the turret of the Coyote light armoured reconnaissance vehicle. The system processes the sound signals and shows the results on a hand-held terminal by means of a graphical and numerical display.

OBS

Ferret provides full 360-degree coverage operating day and night in adverse weather conditions. It has been designed to locate the source of fire up to the effective range of a fired weapon. It calculates the range to the shooter complete coordinates... The system also and the bullet miss distance. The system also generates a digital log of all small arms fire events... When a Global Positioning System(GPS) and an orientation sensor [are] used, Ferret is designed to provide the shooter's complete coordinates... The system also updates the range and azimuth angle to the shooter in real time. This configuration is well adapted to cases where the acoustic array changes direction while under fire.

DEF

Système acoustique passif servant à détecter et à localiser des tirs d'armes légères à grande distance.

OBS

Le système est composé d'un réseau de microphones tridimensionnels monté à l'arrière de la tourelle du véhicule blindé léger de reconnaissance Coyote. Le système traite les signaux sonores et affiche les résultats sur un terminal de poche sous forme graphique et numérique.

OBS

Ferret assure une couverture complète sur 360 degrés, jour et nuit, même par mauvais temps. Il a été conçu pour localiser la source d'un tir sur toute la distance de portée utile d'une arme à feu. Il calcule la distance qui le sépare du tireur ainsi que la distance d'approche de la balle. Le système génère aussi un journal numérique des tirs détectés [...] Couplé au système global de positionnement par satellite (GPS) et à un capteur d'orientation, Ferret est conçu pour fournir les coordonnées complètes [...] du tireur. Le système met également à jour en temps réel la distance et l'angle d'azimut du tireur. Cette configuration est bien adaptée aux situations où le réseau acoustique change d'orientation pendant qu'il essuie le feu ennemi.

English

Subject field(s)
  • Xylology (The Study of Wood)
DEF

A lengthwise separation of the wood that usually extends across the rings of annual growth and commonly results from stresses set up in wood during seasoning.

DEF

A defect found in logs that have been exposed to sun or wind for a long period of time. Sun dries out the wood, causing deep checks on the ends of the log. Heart check, caused by wind, is a radial split along the rays that pass through the center of the log. Weather check is found in logs cut from dead trees. Like sun and wind checks, weather checks are splits in the log, but they are likely to be deeper than the other two.

OBS

check; seasoning check: terms standardized by ISO.

French

Domaine(s)
  • Xylologie (Étude des bois)
OBS

Les gerces longitudinales sont des fissures que l'on observe d'un seul côté des bois débités et qui se forment dans le sens du fil.

OBS

gerce; fente de retrait : termes normalisés par l'ISO.
