Abstract

Dispositif servant à éviter les interférences et utilisé en combinaison avec un système de détection d'une cible de véhicule. La section émetteur-récepteur à micro-ondes (102) du système de détection de cible, dans laquelle l'invention est incorporée, émet et reçoit des signaux micro-ondes multiplexés dans le temps (104) possédant au moins deux canaux (fréquences) espacés d'environ 250 kHz. Le signal d'émission multiplexé dans le temps est émis et heurte des objets (cibles) situés dans l'environnement et une partie du signal d'émission est réfléchie vers l'antenne. Un signal de différence, dont la fréquence est égale à la différence entre la fréquence du signal d'émission et celle du signal de réception, est généré, numérisé et une transformation rapide de Fourier (FFT) s'effectue sur le signal de référence numérisé. Un microcontrôleur (106) analyse le spectre d'énergie, de façon à déterminer la présence d'une interférence. Dans ce cas, le microcontrôleur provoque la modification de la fréquence d'émission, jusqu'à la découverte d'une fréquence relativement exempte de l'interférence.
