- 21 Abstract The invention is directed to a method for classifying vehicles (3) in which an angle resolving radar device (1) yields measurement signals (4) which have frequencies corresponding to the Doppler shift (fD) and which originate from measured vehicles (3) and 5 from which radial distances (RE), object angles (y) and radial velocities can be derived. The frequencies of the acquired measurement signals (4) are stored as functions over the measurement time period (t), and a spectrogram is formed for every vehicle (3) therefrom. Subsequently, the spectrograms are checked for assessment regions (BB) with maximum bandwidth of the frequency. These assessment regions (BB) are compared with assessment 10 regions of stored spectrograms for different vehicle classes and associated with the most similar such that the measured vehicles (3) are classified.
