Abstract

La présente invention concerne un système de localisation d’une source sonore comprenant un goniomètre acoustique équipé de quatre microphones, un circuit de traitement des signaux électriques pour calculer une information représentative de la direction de la source sonore par rapport à ladite antenne acoustique, et un moyen d'imagerie (300) caractérisé en ce qu’il comporte deux goniomètres (100, 200) équipés chacun d’une première paire de microphones (110, 120) et (210, 220) sur un axe XOX’ et une deuxième paire de microphones (130, 140) et (230, 240) sur un axe perpendiculaire YOY’, les microphones de chaque goniomètre (100, 200) étant entourés par une coque acoustiquement transparente (105, 205), chacun desdits goniomètres comportant un circuit électronique pour le traitement des signaux délivrés par chaque microphone et l’exécution par un calculateur d’un traitement d’inter-corrélation entre lesdits signaux de la valeur des décalages temporels des signaux fournis par les microphones. Figure de l’abrégé : figure 1The present invention relates to a system for locating a sound source comprising an acoustic goniometer equipped with four microphones, an electrical signal processing circuit to calculate information representative of the direction of the sound source relative to said acoustic antenna, and a imaging means (300) characterized in that it comprises two goniometers (100, 200) each equipped with a first pair of microphones (110, 120) and (210, 220) on an axis XOX' and a second pair of microphones (130, 140) and (230, 240) on a perpendicular axis YOY', the microphones of each goniometer (100, 200) being surrounded by an acoustically transparent shell (105, 205), each of said goniometers comprising an electronic circuit for the processing of the signals delivered by each microphone and the execution by a calculator of an inter-correlation processing between said signals of the value of the time shifts of the signals supplied by the microphones.
