Abstract

The present disclosure relates to a vehicle radar system (3) adapted to be placed in an ego vehicle (1) and comprising a control unit (4) and at least one transceiver arrangement (5) arranged to generate and transmit an FMCW signal (6; 6a, 6'a; 6b, 6'b) and to receive reflected signals (7) that have been reflected by one or more target objects (14, 15), each target object having an associated determined target object velocity (v₂, v₃). The FMCW signal (6) comprises a corresponding plurality of frequency ramps (r₁, r₂), where each one has a certain duration time (t_r1, t_r2). The control unit (4) is adapted to control the transceiver arrangement (5) to generate at least two pluralities (6a, 6'a; 6b, 6'b, 6c, 6'c) of ramps (r₁, r₂). The ramps (r₁) in each plurality (6a, 6'a) of ramps (r₁) are adapted to have a ramp period time (t_T1) that differs from the ramp period time (t_T2, t_T3, t_T4) in all other pluralities (6b, 6'b, 6c, 6'c) of ramps (r₁, r₂). The ramp period times (t_T1, t_T2, t_T3, t_T4) are based on a determined ego vehicle velocity (v₁), the determined target object velocity (v₂, v₃), or a combination of both.
