Abstract

Méthode d’émission de signaux radio par un radar embarqué au sein d’un véhicule, dispositif et programme d’ordinateur correspondants L'invention concerne une de réduction d’interférences impactant des radars (R1, R2, R3) embarqués dans des véhicules (V1, V2, V3) reposant sur une sélection intelligente et coordonnée de paramètres d’émission (ParSetj) de signaux radio en fonction d’informations contextuelles propres à chaque radar (R1, R2, R3). La solution proposée propose de prendre en compte l’orientation de la ligne de visée du radar (LV1, LV2, LV3) pour déterminer les paramètres d’émission d’un signal radio par le radar (R1, R2, R3). En associant un jeu de paramètres d’émission (ParSetj) d’un signal radio à une orientation du radar(LV1, LV2, LV3), on s’assure que des radars (R1, R2, R3) embarqués dans des véhicules (V1, V2, V3) circulant dans des directions opposées, et ayant donc des orientations opposées se trouvent dans l’incapacité de sélectionner, même fortuitement, des jeux de paramètres d’émission (ParSetj) de signaux radio identiques ou présentant des similitudes telles que les deux signaux pourraient générer des interférences.
