Title (EN) METHOD AND DEVICE FOR DETECTING 1090 ES MESSAGES EMITTED BY AIRCRAFT, SATELLITE COMPRISING SUCH A DETECTION DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTECTION DE MESSAGES 1090 ES ÉMIS PAR DES AÉRONEFS, SATELLITE COMPORTANT UN TEL DISPOSITIF DE DÉTECTION
Abstract:
(EN) The present invention relates to a method (50) for detecting 1090 ES messages comprising the obtaining (51) of an IQ signal, the selection (52) of candidate frequencies for the detection of a 1090 ES message and, for each candidate frequency: - the frequency realignment (53) of the IQ signal with a reference signal comprising a preamble and a 1090 ES message format indicator, - the measurement of resemblance (54) between the reference signal and the IQ signal, so as to obtain a resemblance signal, a 1090 ES message being detected (55) when a value of the resemblance signal satisfies a predetermined detection criterion, and said method comprises the extraction of an ICAO identifier of the aircraft (40) that emitted a detected 1090 ES message, the following 1090 ES messages emitted by said aircraft being detected by means of a reference signal augmented with an emitter identifier equal to the ICAO identifier of said aircraft.
(FR) La présente invention concerne un procédé (50) de détection de messages 1090 ES comportant l'obtention (51) d'un signal IQ, la sélection (52) de fréquences candidates pour la détection d'un message 1090 ES et, pour chaque fréquence candidate : - le recalage fréquentiel (53) du signal IQ avec un signal de référence comportant un préambule et un indicateur de format de message 1090 ES, - la mesure de ressemblance (54) entre le signal de référence et le signal IQ, de sorte à obtenir un signal de ressemblance, un message 1090 ES étant détecté (55) lorsqu'une valeur du signal de ressemblance vérifie un critère prédéterminé de détection, et ledit procédé comporte l'extraction d'un identifiant ICAO de l'aéronef (40) ayant émis un message 1090 ES détecté, les messages 1090 ES suivants émis par ledit aéronef étant détectés au moyen d'un signal de référence augmenté d'un identifiant d'émetteur égal à l'identifiant ICAO dudit aéronef.
