Abstract
Official abstract text for this publication.
A method is described for detecting a rotating wheel of a vehicle that is travelling on a roadway in a travel direction, the wheels of which are at least partially exposed laterally, the method comprising: emitting an electromagnetic measurement beam having a known temporal progression of its frequency onto a first section above the roadway in a direction in a slant with respect to the vertical and normally or at a slant with respect to the travel direction; receiving a reflected measurement beam and recording the temporal progression of its frequencies, relative to the known progression, as a reception frequency mixture progression; and detecting a frequency band, which is continuously inclining or declining over a period of time, in the reception frequency mixture progression as a wheel. A device for conducting the method is also described.
