Summary:In this article, a traffic radar verification system based on the GPS–Doppler technology is described. An speedometer boarded in the target vehicle estimates its speed from the Doppler variation of the GPS satellites signals, and transmits it via radio to the police vehicle, where the radar to verify is located. In order to automate the procedure and be more effective, the detailed system applies artificial vision techniques in recognition of the radar display indication. The GPS–Doppler verifier has been tested operating simultaneously with the previous verification system that is based on the Doppler shift of the radar signal reflected by the target vehicle, which is slower and less precise. The results demonstrate that the new verification system is completely compatible with the previous one.
