An apparatus and method for determining a characteristic feature of a vehicle travelling on a roadway, comprising: a detector, a tracking unit for calculating a target location of the vehicle at a target time on the basis of current location, current time and movement vector, a first radar sensor for transmitting a first radar beam directed towards the current location, receiving a first reflected radar beam and determining a first frequency spectrum thereof, a second radar sensor, connected to the tracking unit, for transmitting a second radar beam directed towards the target location at the target time, receiving a second reflected radar beam and determining a second frequency spectrum thereof, and an evaluation unit for generating the characteristic feature of the vehicle from the determined frequency spectra, wherein the determined frequency spectra constitute the characteristic feature of the vehicle. |
