Abstract

A radar sensor for motor vehicles, having an antenna system that can be controlled by a control device so that it has a temporally varying directional characteristic, and having an evaluation device for evaluating the radar echoes received by the antenna system and for the location of objects using angular resolution, wherein the antenna system has at least two groups of antenna elements that differ in elevation in their effective direction, and the control device is fashioned to activate and deactivate the two groups in periodically alternating fashion, and the evaluation device is configured to estimate the elevation angle of the objects on the basis of a contrast between the radar echoes received by the various groups.
