Patent

CA 2466087

A back-up aid indication system includes a sensor for providing detection coverage in a predetermined coverage zone behind a vehicle. The sensor includes a transmit antenna adapted for transmitting an RF signal having a quasi-collimated antenna pattern in a near field. The system further includes a waveform generator which selectively provides one of a frequency modulated continuous wave FMCW Chirp signal and a pulse waveform signal as the transmitted RF signal.

L'invention porte sur un système indicateur d'assistance au recul comportant un capteur assurant la détection d'objets dans une zone prédéterminée de couverture située derrière un véhicule. Le capteur comporte une antenne conçue pour émettre un signal RF dont le diagramme est quasi collimaté dans le champ proche. Le système comporte en outre un générateur d'onde produisant au choix comme signal RF émis un signal continu modulé en fréquence du type Chirp ou un signal à onde pulsée.
