Abstract:
(EN) According to the invention, a device and a method are provided for determining the position of an object, in particular a moving object, in the three-dimensional space. The device comprises at least two switchable transmitting antennas having a different vertical position of the phase center as well as a plurality of receiving antennas which are arranged in series. The transmitting antennas are arranged in the horizontal direction and at a distance that corresponds to the distance of the receiving antennas. The transmitting antennas are vertically offset with respect to each other by a value that is less than or equal to half the free-space wavelength of the transmitted signal. The transmitting antennas can otherwise be arranged at any position around the receiving antenna. Horizontal beam sweep across a wide angular range is carried out according to the method of "digital beamforming". The measurement of the vertical object position is carried out by phase measurement between the antenna beams when the transmitting antennas are sequentially switched.
(FR) L'invention concerne un dispositif et un procédé pour déterminer la position d'un objet dans un espace tridimensionnel, en particulier d'un objet mobile. Ledit dispositif comporte au moins deux antennes d'émission activables avec une position verticale différente du centre de phase ainsi que plusieurs antennes de réception alignées. Les antennes d'émission sont disposées dans la direction horizontale à un espacement donné les unes des autres, qui correspond à l'espacement des antennes de réception. Dans la direction verticale, les antennes d'émission sont décalées les unes par rapport aux autres à une valeur inférieure ou égale à la moitié de la longueur d'onde en espace libre du signal émis. Sinon, les antennes d'émission peuvent être positionnées de manière quelconque tout autour des antennes de réception. Le balayage de faisceau horizontal sur une plage angulaire étendue est effectué selon la méthode de la « formation de faisceau numérique ». La mesure de la position verticale de l'objet est effectuée par une mesure de phases entre les faisceaux d'antenne lorsque les antennes d'émission sont activées de manière séquentielle.
(DE) Erfindungsgemäß werden eine Vorrichtung und ein Verfahren zur Bestimmung der Position eines Objekts im dreidimensionalen Raum, insbesondere eines sich bewegenden Objekts, zur Verfügung gestellt. Dabei umfasst die Vorrichtung mindestens zwei schaltbare Sendeantennen mit unterschiedlicher vertikaler Position des Phasenzentrums sowie mehrerer in Reihe angeordneter Empfangsantennen. Die Sendeantennen sind dabei in horizontaler Richtung einem Abstand angeordnet, welcher dem Abstand der Empfangsantennen entspricht. In der vertikalen sind die Sendeantennen gegeneinander um einen Wert kleiner gleich der halben Freiraumwellenlänge des gesendeten Signals versetzt. Ansonsten können die Sendeantennen beliebig um die Empfangsantenne herum positioniert werden. Die horizontale Strahlschwenkung über einen weiten Winkelbereich wird nach der Methode des "Digital Beamforming" durchgeführt. Die Vermessung der vertikalen Objektposition erfolgt durch Phasenmessung zwischen den Antennenbeams bei sequentiell geschalteten Sendeantennen.
