Abstract
Techniques are disclosed for determining characteristic feature(s) of a vehicle travelling on a roadway, comprising: a detector, which is directed towards the roadway and is configured to measure the movement vector of the vehicle at a current location and time, a tracking unit, connected to the detector, for calculating a target location of the vehicle at a target time on the basis of current location and time and movement vector, a first radar sensor, connected to the detector, for transmitting a radar beam directed towards the current location, receiving a reflected radar beam, and determining a frequency spectrum thereof, a second radar sensor, connected to the tracking unit, for transmitting a radar beam directed towards the target location at the target time, receiving a reflected radar beam and determining a frequency spectrum thereof, and an evaluation unit for generating characteristic feature(s) of the vehicle from the determined frequency spectra.
