System for scanning an object from a motor vehicle, wherein the system comprises the following: - a first radar apparatus for scanning first information relating to the object and comprising a distance, a first object angle and a first relative speed, wherein the first radar apparatus uses the FMCW method as the measurement principle; - a further radar apparatus in the form of a continuous-wave radar apparatus for scanning second information relating to the object and comprising a second relative speed and a second object angle; and - a processing device for assigning the first and second information relating to the same object, - and for classifying the object on the basis of a characteristic of the second relative speed, wherein - the processing device is configured to carry out a micro-Doppler analysis of the signals from the continuous-wave radar apparatus, - the two radar apparatuses (110, 115) are operated in alternation, - continuous-wave operation is longer than a frequency ramp of FMCW operation, - a differential signal between the emitted continuous-wave radar signal and the continuous-wave radar signal reflected at the object is analysed with respect to its frequency distribution, characterized in that - a temporal profile of the frequency distribution is analysed, - only those frequencies which are below a predetermined cut-off frequency determined on the basis of a speed of the radar apparatuses (110, 115) with respect to an environment are considered, - the analysis is carried out by means of a Fourier transform, - only signal components which are assigned to objects that approach the radar apparatus more quickly than the radar apparatus moves with respect to the environment, that is to say objects which themselves move with respect to the environment, are considered, wherein the Doppler frequency of these objects is accordingly lower, that is to say greater in terms of absolute value, than that Doppler frequency which corresponds to the negative ego-speed. - a first radar apparatus for scanning first information relating to the object and comprising a distance, a first object angle and a first relative speed, wherein the first radar apparatus uses the FMCW method as the measurement principle; - a further radar apparatus in the form of a continuous-wave radar apparatus for scanning second information relating to the object and comprising a second relative speed and a second object angle; and - a processing device for assigning the first and second information relating to the same object, - and for classifying the object on the basis of a characteristic of the second relative speed, wherein - the processing device is configured to carry out a micro-Doppler analysis of the signals from the continuous-wave radar apparatus, - the two radar apparatuses (110, 115) are operated in alternation, - continuous-wave operation is longer than a frequency ramp of FMCW operation, - a differential signal between the emitted continuous-wave radar signal and the continuous-wave radar signal reflected at the object is analysed with respect to its frequency distribution, characterized in that - a temporal profile of the frequency distribution is analysed, - only those frequencies which are below a predetermined cut-off frequency determined on the basis of a speed of the radar apparatuses (110, 115) with respect to an environment are considered, - the analysis is carried out by means of a Fourier transform, - only signal components which are assigned to objects that approach the radar apparatus more quickly than the radar apparatus moves with respect to the environment, that is to say objects which themselves move with respect to the environment, are considered, wherein the Doppler frequency of these objects is accordingly lower, that is to say greater in terms of absolute value, than that Doppler frequency which corresponds to the negative ego-speed.
