Abstract

On provoque l'émission depuis un emplacement-cible (12) d'une impulsion acoustique courte, de première durée. On recueille sur un réseau de transducteurs (14) et on enregistre, pendant une seconde durée, supérieure d'au moins un ordre de grandeur à la première durée, les signaux acoustiques provenant dudit emplacement à travers un milieu multi-diffuseur (10). On émet vers le milieu multi-diffuseur, à partir des transducteurs (14), des signaux de retour obtenus par inversion temporelle et amplification de ceux recueillis pendant la seconde durée, ce qui provoque une focalisation et une compression temporelle d'énergie acoustique à l'emplacement-cible.
