Abstract
(DE)
Zur Messung der Winkellage (&agr;) eines entfernten Objektes, wird ein Radarsystem (RS) vorgestellt, welches umfasst: - eine Antenne (A) mit mindestens zwei Empfangsantennen (EA1 , EA2) ; - einen Sender (Tx) , welcher zur Aussendung eines Sendesignals mit der Antenne (A) verbunden ist; - einen ersten Empfänger (Rx1) , welcher zum Empfangen eines als ein erstes Empfangssignal von dem entfernten Objekt reflektierten Sendesignals mit einer ersten der mindestens zwei Empfangsantennen (EA1, EA2) verbunden ist; - einen zweiten Empfänger (Rx2) , welcher zum Empfangen eines als ein zweites Empfangssignal von dem entfernten Objekt reflektierten Sendesignals mit einer zweiten der mindestens zwei Empfangsantennen (EAl, EA2) verbunden ist, dadurch gekennzeichnet, dass - der erste Empfänger (Rx1) ein erstes Mittel zur Ermittlung einer ersten Phase des ersten Empfangssignals umfasst und - der zweite Empfänger (Rx2) ein zweites Mittel zur Ermittlung einer zweiten Phase des zweiten Empfangssignals umfasst.
(EN)
The invention relates to a radar system (RS) for measuring the angular position (a) of a remote object comprising an antenna (A) which is provided with at least two receiving antenna (EA1, EA2), a transmitter (Tx) which his connected to the antenna (A) for transmitting a transmitted signal, a first receiver (Rx1) which is connected to the first reception antenna (EA1, EA2) for receiving the transmitted signal reflected by the remote object in the form of a first received signal and a second receiver (Rx2) which is connected to the second reception antenna (EA1, EA2) for receiving the transmitted signal reflected by the remote object in the form of a second received signal. The inventive radar system is characterised in that the first receiver (Rx1) is provided with a first element for determining the first phase of the first received signal and the second receiver(Rx2) is provided with a second element for determining the second phase of the second received signal
(FR)
L'invention concerne un système radar (RS) destiné à mesurer la position angulaire ($g(a)) d'un objet distant, comportant une antenne (A) présentant au moins deux antennes de réception (EA1, EA2) ; un émetteur (Tx) connecté à l'antenne (A) pour l'émission d'un signal d'émission ; un premier récepteur (Rx1) connecté à une de deux antennes de réception (EA1, EA2) pour la réception d'un signal d'émission réfléchi par l'objet distant en tant que premier signal de réception ; et, un deuxième récepteur (Rx2) connecté à une deuxième antenne de réception (EA1, EA2) pour la réception d'un signal d'émission réfléchi par l'objet distant en tant que deuxième signal de réception. Le système radar selon l'invention est caractérisé en ce que le premier récepteur (Rx1) comporte un premier élément de détermination d'une première phase du premier signal de réception, et le deuxième récepteur (Rx2) comporte un deuxième élément de détermination d'une deuxième phase du deuxième signal de réception.
