Abstract: An automotive radar system (100) including first and second radar sensors (110, 120) transmitting a radar signal, and a processor (130). Each radar sensor (110, 120) determines ranges to one or more targets (140), where each determined range is associated with a complex value (Vmn) in a range vector. The processor (130) determines a difference in the ranges determined by the first and second radar sensors (110, 120). The processor (130) converts the difference in ranges to an intermediate frequency, IF, phase value (?IF) by relating the difference in ranges to the radar bandwidth (BW). The processor (130) adjusts the complex values (Vmn) in the range vectors by the IF phase value (?IF) and determines an angle (a) to at least one of the targets (140) based on the adjusted complex values in the range vectors from each radar sensor (110, 120).
