    摘要: The present disclosure relates to a vehicle radar system (3) arranged to be mounted in a host vehicle (1) arranged to run in a forward running direction (D). The vehicle radar system (3) comprises at least one transceiver arrangement (7) arranged to generate and transmit radar signals (4), and to receive reflected radar signals (5), where the transmitted radar signals (4) have been reflected by one or more objects (6, 12). The radar system (3) is arranged to provide range (r n ), azimuth angle (θ n ) and radial velocity (v rn ) for a plurality of measurement points (9, 9') at said objects (6, 12). The radar system (3) is furthermore arranged to divide a total detection volume (8) into at least two partial volumes (8a, 8b, 8c, 8d), and to perform a velocity estimation for each partial volume (8a, 8b, 8c, 8d) such that a total velocity distribution (14) is acquired along a side extension (E) that is perpendicular to an extension along the forward running direction (D).
