Patent attributes
Angle-resolving radar sensor for motor vehicles, including: an antenna array including multiple antennas, configured for receiving, situated in various positions in one direction in which the radar sensor is angle-resolving, and a control and evaluation unit configured for an operating mode in which at least one antenna of the radar sensor configured for transmitting transmits a signal received by multiple of the antennas of the radar sensor configured for receiving, and the angle of a radar target is estimated based on amplitude and/or phase relationships between signals of respective evaluation channels, which correspond to different configurations of transmitting and receiving antennas, an evaluation of the signals of the evaluation channels for a respective distance for a respective evaluation channel taking place for an individual estimation of an angle of a radar target, different distances being selected for respective evaluation channels as a function of an angle or angle range hypothesis.
