Title (EN) ACOUSTIC POSITION-DETERMINATION SYSTEM
(FR) SYSTÈME ACOUSTIQUE DE LOCALISATION
Abstract:
(EN) The position of a mobile unit (12) within a detection zone is determined. An acoustic signal is emitted from the mobile unit and received along a first path (54). An echo of the signal is received after reflection from a surface (46) within said detection zone. The position of the mobile unit (12) within the detection zone is determined from the times of arrival of the signal and echo.
(FR) La position d'une unité mobile (12) dans une zone de détection est déterminée. Un signal acoustique est émis par l'unité mobile et reçu le long d'un premier passage (54). Un écho du signal est reçu après réflexion sur une surface (46) se trouvant à l'intérieur de ladite zone de détection. La position de l'unité mobile (12) dans la zone de détection est déterminée à partir des instants d'arrivée du signal et de l'écho.
