Title (EN) RADAR SYSTEM COMPRISING AN ANTENNA ARRANGEMENT FOR TRANSMITTING AND RECEIVING ELECTROMAGNETIC RADIATION
(FR) SYSTÈME DE RADAR, COMPORTANT UN ENSEMBLE D’ANTENNES POUR ÉMETTRE ET RECEVOIR UN RAYONNEMENT ÉLECTROMAGNÉTIQUE

Abstract:
(EN) The invention relates to a radar system comprising an antenna arrangement (1) which is intended to transmit and receive electromagnetic radiation, wherein N first antennas (4) are provided for transmission and M second antennas (5) are provided for reception and objects in the capture range of the antennas (4, 5) are detected according to the MIMO principle using the N first transmitting antennas (4) and using the M second receiving antennas (5). Provision is also made for the N first transmitting antennas (4) to emit transmission signals which are orthogonal to one another in a transmitting cycle, for N-n of the N first transmitting antennas (10, 11) to be arranged horizontally beside one another and for at least n of the N first transmitting antennas (12, 13) to be arranged in a vertically offset manner with an offset which is the same in each case with respect to the N-n transmitting antennas (10, 11) which are arranged horizontally beside one another, and for M-m of the M second receiving antennas (14, 15, 16, 17) to be arranged horizontally beside one another and for at least m of the M second receiving antennas (19, 20, 21) to be arranged in a vertically offset manner with respect to the M-m receiving antennas (14, 15, 16, 17) which are arranged horizontally beside one another.
(FR) L'invention concerne un système de radar qui comporte un ensemble d’antennes (1) qui permet l’émission et la réception d’un rayonnement électromagnétique et comprend N premières antennes d’émission (4) pour l’émission et M secondes antennes de réception (5) pour la réception, des objets dans la plage de détection des antennes (4, 5) étant détectés selon le principe MIMO avec les N premières antennes d’émission (4) et avec les M secondes antennes de réception (5). Selon l’invention, les N premières antennes d’émission (4) émettent des signaux d’émission orthogonaux les uns par rapport aux autres dans un cycle d’émission, N-n des N premières antennes d’émission (10, 11) sont disposées horizontalement les unes à côté des autres et au moins n des N premières antennes d’émission (12, 13) sont disposées de manière décalée verticalement, avec chacune le même écart, par rapport aux N-n antennes d’émission (10, 11) disposées horizontalement les unes à côté des autres et M-m des M secondes antennes de réception (14, 15, 16, 17) sont disposées horizontalement les unes à côté des autres et au moins m de M secondes antennes de réception (19, 20, 21) sont disposées de manière décalée verticalement, avec chacune le même écart, par rapport aux M-m antennes de réception (14, 15, 16, 17) disposées horizontalement les unes à côté des autres.
(DE) Gegenstand der Erfindung ist ein Radarsystem, das eine Antennenanordnung (1) umfasst, die zum Senden und Empfangen elektromagnetischer Strahlung vorgesehen ist, wobei N erste Antennen (4) zum Senden und M zweite Antennen (5) zum Empfangen vorgesehen sind und mit den N ersten Sendeantennen (4) und mit den M zweiten Empfangsantennen (5) Objekte im Erfassungsbereich der Antennen (4, 5) nach dem MIMO-Prinzip detektiert werden. Weiterhin ist vorgesehen, dass die N ersten Sendeantennen (4) in einem Sendezyklus zueinander orthogonale Sendesignale aussenden, dass N-n der N ersten Sendeantennen (10, 11) horizontal nebeneinander angeordnet sind und mindestens n der N ersten Sendeantennen (12, 13) gegenüber den N-n horizontal nebeneinander angeordneten Sendeantennen (10, 11) mit einem jeweils gleichen Versatz vertikal versetzt angeordnet sind und dass M-m der M zweiten Empfangsantennen (14, 15, 16, 17) horizontal nebeneinander angeordnet sind und mindestens m der M zweiten Empfangsantennen (19, 20, 21) gegenüber den M-m horizontal nebeneinander angeordneten Empfangsantennen (14, 15, 16, 17) vertikal versetzt angeordnet sind.
