摘要： The present invention relates to a vehicle radar system (2) arranged to detect objects outside a vehicle (1). The radar system (2) comprises a radar detector (3) and a processing unit (4). The processing unit (4) is arranged to obtain values for detected target angle (Θerr) and detected target Doppler velocity (v d ) relative the radar detector (3) for each detected object (10a', 10b', 10c', 10d', 10e' ) during a certain time interval. If there is a zero crossing (14) for a derivative (13) of a function (12) describing the progression of detected target Doppler velocity (v d ) as a function of detected target angle (©err), the processing unit (4) is arranged to detect said zero crossing (14). This zero crossing (14) is indicative of a radar system misalignment (Θm). The present invention also relates to a corresponding method.

摘要： The present disclosure relates to a vehicle radar system (3) comprising a first and second radar sensor arrangement (4a, 4b). Each radar sensor arrangement (4a, 4b) comprises at least two transmitter antenna devices (10a1, 10a2) and at least two receiver antenna devices (13a1, 13a2, 13a3, 13a4), where each receiver antenna device (13a1, 13a2, 13a3, 13a4 ) has a corresponding boresight extension (46a, 46b) that is perpendicular to an antenna plane (57). Each receiver antenna device (13a1, 13a2, 13a3, 13a4 ) has a corresponding antenna radiation pattern (47a, 47b) that has a lower gain (48a, 48b) in its boresight extension (46a, 46b) than at a certain corresponding first maximum gain azimuth angle (φ1a, φ1b) where there is a first maximum gain (49a, 49b). Each radar sensor arrangement (4a, 4b) is mounted such that each first maximum gain (49a, 49b) is directed along a corresponding first maximum gain extension (51a, 51b), such that an overlap part (56) of the antenna radiation patterns (47a, 47b) is formed.
