Abstract

L'invention concerne un système doté de la capacité à acquérir une signature acoustique avec une précision élevée, pouvant être utilisé pour identifier une artillerie ou d'autre sources d'onde de choc explosive à partir de leur signature acoustique. Ce système comprend deux microphones (20, 22) à performances élevées, l'un agissant en tant que microphone déclencheur (22). Ce microphone (22) est placé dans une chambre spéciale (12) contenant un panneau ou une paroi flottante (14), inséré de telle façon à pouvoir librement vibrer légèrement. Tout signal acoustique impulsionnel provoque l'établissement d'une pression interne d'impulsion qui fait démarrer une acquisition de données. Après filtrage anti-repliement et numérisation, le signal provenant du microphone de mesure (20) est traité de telle manière que l'on peut en extraire certains paramètres. Les plus significatifs de ces paramètres sont le 'nombre de Mach modifié', le 'niveau d'intensité sonore', le 'potentiel d'énergie d'onde de choc acoustique' et le 'nombre de largeur de bande de fréquence'. Ils peuvent être portés sur un graphique afin de produire une 'structure de décision' bidimensionnelle et une 'fonction de décision' bidimensionnelle ou tridimensionnelle, qui peuvent être utilisées afin d'identifier l'origine de l'onde choc impulsionnelle ou explosive.
