Abstract

The present disclosure relates to a vehicle radar system (3) comprising a control unit (4) and at least one transceiver arrangement (5), for transmitting radar signals (6) and receiving reflected signals (7), The vehicle radar system (3) is adapted to identify at least one ground stationary target object (8), and to follow the ground stationary target object (8) for a plurality of times (t<1>-t<5>). For at least two different values of a parameter (v<host>, ω, θ<GND>) related to, or affected by, vehicle dynamics or vehicle statics for a host vehicle (1), the control unit (4) is adapted to calculate a coherently integrated complex signal representing the detected ground stationary target object (8<t1>, 8<t2>, 8<t3>, 8<t4>, 8<t5>) for the plurality of times (t<1>-t<5>) using said parameter (v<host>, ω, θ<GND>) such that a resulting signal magnitude (A<1>, A<2>, A<3>, A<4>, A<5>) is obtained. The control unit (4) is further adapted to compare the resulting signal magnitudes (A<1>, A<2>, A<3>, A<4>, A<5>), and to choose the parameter value (v<host3>) that is associated with the highest signal magnitude (A<4>, A<t5>) as the most correct parameter value.
