Abstract

A radar sensor includes one transmitting antenna, multiple first receiving antennas with the same vertical heights, and a second receiving antenna with a vertical height different from the others. A method for determining the azimuth angle of an object with respect to the radar sensor includes steps of determining an approximation for the azimuth angle in a coarse grid based on the signals of all receiving antennas, and determining the azimuth angle in a fine grid based on the signals of the first receiving antennas in a range around the approximation.
