Abstract
A method for identifying an elevation misalignment angle of a radar sensor of a vehicle, including: identifying elevation angles of radar object localizations with reference to a coordinate system of the radar sensor, an elevation angle of a radar object localization being respectively identified based on radar echoes that are obtained with at least two antenna directional characteristics that differ in an elevation direction; and identifying an elevation misalignment angle based on an occurrence frequency distribution of the elevation angles of at least some of the radar object localizations; and a radar sensor for vehicles having an evaluation device embodied to carry out the method.
