Method and arrangement for evaluating signals or data of an object detection system

It is an object detection system, proposed in particular for a motor vehicle, in which a radar sensor, from the object reflected radar signals for determining the distance (d) and / or the relative or approximate velocity (Cv) of the object processed. The digital signals at least one channel (I, Q) of the radar sensor are so far processed until a first evaluation way as distance (d), or as a proximity speed signal (Cv) results and there is a mode switch (4) for the evaluation as the distance ( (d) or as an approximation velocity signal Cv) is determined with the determined what data and an interface (6) between the radar sensor and a downstream control device (7) are provided.
