Abstract
(DE) MIMO-Radarsensor für Kraftfahrzeuge, mit einer Antennenanordnung (10) auf einer rechteckigen Platine (16), deren Kanten eine y-Richtung und eine z- Richtung definieren, wobei die Antennenanordnung mindestens zwei Arrays (TA1, TA2) von Sendeantennen (TX) und mindestens zwei Arrays (RA1, RA2) von Empfangsantennen (RX) umfasst, die Sendeantennen (TX) innerhalb jedes Arrays in z-Richtung gegeneinander versetzt sind, während die beiden Arrays (TA1, TA2) der Sendeantennen in y-Richtung gegeneinander versetzt sind, und die Empfangsantennen (RX) innerhalb jedes Arrays in y-Richtung gegeneinander versetzt sind, während die beiden Arrays (RA1, RA2) der Empfangsantennen in z-Richtung gegeneinander versetzt sind, dadurch gekennzeichnet, dass die beiden Arrays (TA1, TA2) der Sendeantennen benachbart zu zwei einander gegenüberliegenden Kanten der Platine (16) angeordnet sind, die beiden Arrays (RA1, RA2) der Empfangsantennen benachbart zu den beiden übrigen Kanten der Platine (16) angeordnet sind und in einem mittleren Bereich der Platine (16) zwischen den Arrays der Sende- und Empfangsantennen mindestens ein Hochfrequenzbaustein (18) auf der Platine angeordnet ist.
(EN) The invention relates to a MIMO radar sensor for motor vehicles, comprising an antenna assembly (10) on a rectangular circuit board (16), the edges of which define a Y-direction and a Z-direction, wherein the antenna assembly has at least two arrays (TA1, TA2) of transmitting antennas (TX) and at least two arrays (RA1, RA2) of receiving antennas (RX), said transmitting antennas (TX) being offset in relation to one another in the Z-direction within every array, while the two arrays (TA1, TA2) of the transmitting antennas are offset in relation to one another in the Y-direction, and said receiving antennas (RX) being offset in relation to one another in the Y-direction within every array, while the two arrays (RA1, RA2) of the receiving antennas are offset in relation to one another in the Z-direction, characterised in that the two arrays (TA1, TA2) of the transmitting antennas are arranged adjacent to two opposing edges of the circuit board (16), the two arrays (RA1, RA2) of the receiving antennas are arranged adjacent to the two remaining edges of the circuit board (16), and at least one high-frequency component (18) is arranged on the circuit board in a central region of the circuit board (16) between the arrays of the transmitting and receiving antennas.
