Abstract

A method for localizing at least one object (7) in surroundings (8) of a motor vehicle (1) by a radar sensor device (2) of the motor vehicle (1), comprising the steps of: emitting radar radiation signals (9) into the surroundings (8) by a plurality of sending antennas (3) of the radar sensor device (2), wherein the plurality of sending antennas (3) is distributed attached at the motor vehicle (1); capturing radar radiation signals (10), which were reflected by the at least one object (7), by a plurality of receiving antennas (4) of the radar sensor device (2)(, wherein the plurality of receiving antennas (4) is distributed attached at the motor vehicle (1); generating a delay-doppler map (13) for the surroundings (8) depending on the emitted radar radiations signals (9) and the received radar radiation signals (10) by an electronic computing device (5) of the radar sensor device (2); applying a nearfield-beaming algorithm on the generated delay-doppler map (13) by the electronic computing device (5); generating a range-angle map (15) depending on the applied nearfield-beamforming algorithm by the electronic computing device (5); and localizing the at least one object (7) in the range-angle map (15) by the electronic computing device (5). Furthermore, the present invention relates to a computer program product, a computer-readable storage medium, as well as to a radar sensor device (2).
