Title (EN) AIRCRAFT ACOUSTIC POSITION AND ORIENTATION DETECTION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE DÉTECTION D'ORIENTATION ET DE POSITION ACOUSTIQUE D'AÉRONEF
Abstract:
(EN) A method for determining position of an aircraft with reference to a location on the ground includes transmitting an acoustic signal from a position on the aircraft to an array of spaced apart acoustic sensors proximate the location. The method includes at least one of (i) determining a time difference of arrival of the acoustic signal between each of the acoustic sensors and a reference acoustic sensor and (ii) determining an arrival time of the acoustic signal at each of the spaced apart acoustic sensors. The position of the aircraft is determined from the time differences of arrival and/or the arrival times.
(FR) La présente invention concerne un procédé de détermination de la position d'un aéronef en référence à un emplacement au sol consistant à transmettre un signal acoustique d'une position sur l'aéronef à un réseau de capteurs acoustiques espacés à proximité de l'emplacement. Le procédé consiste en (i) la détermination d'une différence de temps d'arrivée du signal acoustique entre chacun des capteurs acoustiques et un capteur acoustique de référence et/ou (ii) la détermination d'un temps d'arrivée du signal acoustique au niveau de chacun des capteurs acoustiques espacés. La position de l'aéronef est déterminée à partir des différences de temps d'arrivée et/ou des temps d'arrivée.
