Speed enforcement on roadways has been partiallysolved using radar and/or laser technologies, and more recently,using video-camera based systems. The main drawback ofclassical Doppler radar technology is that the velocitymeasurement fails when several vehicles are in the radar’sbeam. Modern radar systems are able to measure speed andrange between vehicle and radar; however, this is not enough todiscriminate the lane where the vehicle is driving on. Road laneidentification is overcome using laser technology; however,laser systems can not measure the speed of several vehicles atthe same time. Novel video-camera systems, based on licenseplate identification, solve the previous shortcomings, but theycan only measure average speed, never top-speed. This paperstudies the feasibility of using radar interferometry to improvetop-speed enforcement. This allows measuring simultaneouslyspeed, range and lane of several vehicles, i.e., univocalidentification of the offender vehicles.
