Abstract

All existing traffic radars to be used for speed enforcement measure the speed of the passing vehicles on the basis of a CW technology. A new prototype of a traffic radar sensor has been developed that not only measures the speed of the vehicle but also its distance to the radar device. The measured distance enables the police to unambiguously assign the measured speed to a vehicle shown in a picture, even in special cases. The prototype is based on a 77 GHz pulse radar technology that has so far been used only for driver assistance systems. In a first step, the accuracy of an existing sensor was analysed by comparing the results with a reference system for speed measurements. In a second step, the sensor was modified in order to optimise it for speed enforcement, and tested again. The concept of the prototype, the modifications and the results of the comparison are described. For the covering abstract see ITRD E114174.
