USE OF ENHANCEMENT PLATES FOR IMPROVED DOPPLER RADAR PERFORMANCE FOR GROUND TRANSPORT SYSTEMS

A method of improving the performance of X-Band Doppler radars for ground transport vehicles is presented. The technique utilizes small metallic reflectors placed directly below the guideway surface. From the results of preliminary laboratory and on-road tests it is concluded that improved accuracy of on-board position and velocity measurements result. In the safe operation of high-speed short time-headway automatically controlled ground transport systems, there is a need for highly accurate position and velocity sensors. Since the advent of low-cost solid-state X-band sources, much attention has been focused on the use of Doppler radars operating with the rough-surface backscattered signal from the roadway as velocity sensors for ground-based vehicles. The results to date indicate that, while the method may be adequate for conventional applications, some improvement is needed before these radars can be used in high-capacity automated transit systems.
