Title (DE) KRAFTFAHRZEUG-RADARSENSOR
(EN) RADAR SENSOR FOR A VEHICLE
(FR) CAPTEUR-RADAR POUR VEHICULE
Abstract:
(DE) Es wird ein kompakter, mehrstrahliger und in einem Gehäuse untergebrachter Kraftfahrzeug-Radarsensor beschrieben mit einer Antennenanordnung, bestehend aus einem fokussierenden Mittel (15) und mindestens zwei ersten Antennenfeeds (161-163, 181-183), die entlang einer ersten Geraden (20) angeordnet sind und eine erste Reihe von Antennenfeeds bilden, bei dem mindestens ein weiteres Antennenfeed (164-165, 184-185) vorhanden ist, das so angeordnet ist, daß entlang einer weiteren Geraden (21) mindestens eine weitere Reihe von Antennenfeeds gebildet wird, wobei diese weitere Reihe durch eine Drehung um einen angenommenen Drehpunkt (M) kongruent auf die erste Reihe abbildbar ist. Ein solcher Kraftfahrzeug-Radarsensor kann sehr einfach und kostengünstig an verschiedene Einbaulagen angepaßt werden.
(EN) The invention pertains to a compact, multibeam and self-contained radar sensor for a vehicle, with an antenna installation comprising a focussing element (15) and at least two first feeds (161-163, 181-183) arranged along a first straight (20) so as to form a first series of feeding units, while at least one additional antenna feeding unit (164-165, 184-185) is installed in such a way that along another straight (21) is at least a further series of feeding units. One series of feeding units can be reversed upon the other so as to be mutually congruent by rotation about a set point (M). A radar sensor for a vehicle, such as suggested by the invention, can easily be adapted at a low cost to various installation positions.
(FR) La présente invention porte sur un capteur-radar pour véhicule, compact, multifaisceaux et logé dans un boîtier, avec un sytème d'antenne comportant un élement de focalisation (15) et au moins deux premiers systèmes d'alimentation (161-163, 181-183) disposés le long d'une première droite (20) de manière à former une première série d'unités d'alimentation, au moins une autre unité d'alimentation (164-165, 184-185) d'antenne étant installée de telle manière que le long d'une autre droite (21) se trouve au moins une autre série d'unités d'alimentation, laquelle peut se renverser en harmonie sur la première par rotation autour d'un point établi (M). Un capteur-radar pour véhicule, tel que proposé, peut s'adapter très facilement et pour un coût avantageux à différentes positions d'installation.
