Title (DE) FMCW-RADARSENSOR FÜR KRAFTFAHRZEUGE
(EN) FMCW RADAR SENSOR FOR MOTOR VEHICLES
(FR) DÉTECTEUR DE RADAR FMCW POUR VÉHICULES AUTOMOBILES
Abstract:
(DE) FMCW-Radarsensor für Kraftfahrzeuge, mit mindestens einem Antennenelement (14) und einer Modulationseinrichtung (22, 24, 30) zum Speisen des Antennenelements (14) mit einem frequenzmodulierten Sendesignal, dessen Frequenz periodisch ein Frequenzband überstreicht, dadurch gekennzeichnet, daß das Antennenelement (14) mehrere in einer vertikalen Spalte angeordnete und seriell gespeiste Subelemente (32) aufweist und daß die Modulationseinrichtung (30, 22, 24) dazu ausgebildet ist, die Frequenzlage des Frequenzbandes variabel einzustellen.
(EN) The invention relates to a FMCW radar sensor for motor vehicles, comprising at least one antenna element (14) and one modulation device (22, 24, 30) for feeding a frequency-modulated transmission signal to the antenna element (14), the frequency of which periodically exceeds a frequency band, characterized in that the antenna element (14) comprises a plurality of subelements (32) arranged in a vertical gap and being fed in series and the modulation device (30, 22, 24) is designed to variably set the frequency position of the frequency band.
(FR) L'invention concerne un détecteur de radar FMCW pour véhicules automobiles, avec au moins un élément d'antenne (14) et un dispositif de modulation (22, 24, 30) destiné à alimenter l'élément d'antenne (14) avec un signal d'émission modulé en fréquence, dont la fréquence balaie périodiquement une plage de fréquences. Selon l'invention, l'élément d'antenne (14) comprend plusieurs sous-éléments (32) disposés dans une fente verticale et alimentés en série. Le dispositif de modulation (30, 22, 24) est configuré pour faire varier la position de la bande de fréquences.
