Abstract : This paper investigates the influence of rotating applications, such as ACC Adaptive Cruise Control or FCW steel platform in the RCS Radar Cross Section measurement of Forward Collision Warning. vehicles at 22-26 GHz for automotive radar application. Across several measurement steps, we compare different RCS measurement results in order to eliminate the undesired RCS contribution caused mainly by the rotating steel platform. We demonstrate that when it is difficult or impossible to use microwave absorbers on the steel platform, an alternative scan symmetry of vehicle of target vehicle, the VUT should method can be applied. Finally, with the help of 2D radar image be positioned on a rotating steel platform. The RCS measurement configuration could be described as follows. As in a real road cruising situation, we carry out RCS measurements in outdoor conditions. Secondly, considering the weight of VUT, and the need of a continuous 180° azimuth post processing, we can also identify and separate the RCS contribution of each element vehicle, steel platform, ground-multipath-clutter in the hologram image, and therefore obtain the pure RCS distribution of the tested vehicle.
