Abstract: A vehicle radar system (3, 3′) and related method including a transceiver arrangement (7, 7′) that is arranged to generate and transmit at least a first radar signal over a cycle (4a) and a following second radar signal over a cycle (4b). For the first radar signal cycle (4a), a corresponding first received signal (5a) and corresponding first received signal information (20a, 28a) is obtained, and for a following second radar signal cycle (4b), a corresponding second received signal (5b) and corresponding second received signal information (20b, 28b) is obtained. The vehicle radar system (3, 3′) is arranged to calculate a difference between the first received signal information (20a, 28a) and the second received signal information (20b, 28b).
