Abstract

The present disclosure relates to a vehicle radar system (2) that comprises a radar detector (3) that is arranged to detect at least one stationary object (10) a plurality of times when a vehicle (1) moves in relation to it. A plurality of detected positions (11, 12, 13) are obtained in a local coordinate system (15), fixed with respect to the radar detector (3). The object (10) is stationary with respect to a global coordinate system (16), fixed with respect to the outside environment. A position detector (14) is arranged to detect its present movement conditions with reference to the global coordinate system (16). Correction factors are applied on each detected position of the object in the local coordinate system (15). All obtained corrected detected positions are then transformed into the global coordinate system (16) and an error/cost value is calculated for each correction factor. The correction factor that results in the smallest error/cost value is chosen.
