Abstract
(DE)
Radarsystem für ein Fahrzeug, aufweisend: • - wenigstens zwei Sendeantennen (20) jeweils zur Aussendung eines Sendesignals in eine Umgebung des Fahrzeuges, • - wenigstens vier Empfangsantennen (30) jeweils zur Erfassung eines Erfassungssignals zur Detektion von Zielen in der Umgebung des Fahrzeuges, • - eine Verarbeitungsvorrichtung zur Sichtwinkelbestimmung, um eine Phaseninformation bei den Erfassungssignalen wenigstens einem Sichtwinkel für jeweilige detektierte Ziele zuzuordnen, sodass ein Uneindeutigkeitsmindestabstand (du) der Empfangsantennen (30) in einer ersten Richtung (RI) dafür spezifisch ist, dass die Zuordnung mehrdeutig zu mehr als einem Sichtwinkel erfolgt, wobei sämtliche der Empfangsantennen (30) in der ersten Richtung (RI) mit unterschiedlichen Abständen zueinander angeordnet sind, sodass nur einer der Abstände dem Uneindeutigkeitsmindestabstand (du) entspricht.
(EN)
A radar system for a vehicle, having: • - at least two transmission antennas (20), each for emitting a transmission signal into the surroundings of the vehicle, • - at least four reception antennas (30), each for acquiring a detection signal for detecting targets in the surroundings of the vehicle, • - a processing device for determining the viewing angle, in order to assign phase information in the detection signals to at least one viewing angle for respective detected targets, so that an ambiguity minimum distance (du) of the reception antennas (30) in a first direction (RI) is specific for the fact that the assignment is made ambiguously to more than one viewing angle, wherein all of the reception antennas (30) in the first direction (RI) are arranged at different distances from one another, so that just one of the distances corresponds to the ambiguity minimum distance (du).

L'invention concerne un système radar destiné à un véhicule, qui comporte : au moins deux antennes d'émission (20) servant respectivement à émettre un signal d'émission dans un environnement du véhicule ; au moins quatre antennes de réception (30) servant à détecter respectivement un signal de détection servant à la détection de destinations dans l'environnement du véhicule ; un dispositif de traitement servant à définir l'angle de vue afin d'associer une information de phase pour les signaux de détection à au moins un angle de vue pour des destinations respectives détectées de sorte qu'un espacement minimal ambigu (du) entre les antennes de réception (30) dans une première direction (RI) est propre au fait que l'association à plus d'un angle de vue est équivoque, toutes les antennes de réception (30) étant disposées les unes par rapport aux autres dans la première direction (RI) selon des espacements différents si bien que seul un des espacements correspond à l'espacement minimal ambigu (du).
