Method and apparatus for monitoring the speed of vehicles using a Doppler radar speed measuring device, and application of the method

摘要

After a vehicle has driven into the radar beam, a first measured speed value (V*) is determined and subsequently verified (VERIFICATION). If, after successful verification, the first measured speed value (V*) overshoots a specific limiting value, the vehicle is registered. Following the verification (CHECK) a search is made for further measured speed values, which are compared, as the case may be, with the first measured speed value (V*). Depending upon the result of said comparison, there is a confirmation or annulment of the measurement and/or registration. Erroneous measurements caused by so-called multiple reflections can be recognised by the additional check (CHECK). IMAGE
