    摘要: The invention relates to a multibeam radar sensor apparatus having at least two transmission/reception channels, the signal paths of which each contain an antenna and a mixer, wherein at least one first mixer is designed in a bidirectional manner as a transfer mixer and at least one second mixer can be switched from a first operating state to a second operating state, wherein the mixer is designed in a bidirectional manner as a transfer mixer in the first operating state and is designed in an at least approximately insulating manner as a receiving mixer in the second operating state. The invention also relates to a method for determining a distance and/or a speed of a target, in which a radar signal is transmitted in the direction of the target and a reflected radar echo is received, for which use is made of at least two transmission/reception channels, the signal paths of which each contain an antenna and a mixer, wherein at least one mixer is switched from a first operating state to a second operating state in order to use the mixer in a bidirectional manner as a transfer mixer in the first operating state and in an at least approximately insulating manner as a receiving mixer in the second operating state.

    摘要: Radar sensor for motor vehicles, having an antenna arrangement (Rx, Tx1, Tx2) which can be actuated by a control device (28) in such a way that it has a chronologically varying directional characteristic, and having an evaluation device (26) for evaluating the radar echoes received by the antenna arrangement and for locating objects with angular resolution, characterized in that the antenna arrangement has at least two groups (Tx1, Tx2) of antenna elements (12, 14) which differ in elevation in terms of their direction of action, in that the control device (28) is designed to activate and deactivate the two groups (Tx1, Tx2) alternately, and in that the evaluation device (26) is designed to estimate the elevation angle (a) of the objects (22) by means of a contrast (K) between the radar echoes received by the various groups (Tx1, Tx2).

    摘要: The invention relates to a radar sensor device having at least one planar antenna arrangement, which comprises a plurality of vertically oriented antenna columns (15b, 15c, 15d) arranged as a sparse array (15.2) on a plane parallel to one another at defined distances from each other. Each antenna column has at least two line-fed patch elements (23), wherein the sparse array (15.2) of antenna columns (15b, 15c, 15d) is configured with minimal redundancy such that the total number of the defined distances between the antenna columns (15b, 15c, 15d) in the sparse array (15.2) is at least equal to all the different distances between any two antenna columns of a corresponding non-sparse array of a planar antenna arrangement having the same antenna aperture and the same antenna column characteristics, but is kept as low as possible.
