The system consists of simple beacons, which are entirely passive and fixed along the rails according to the required codes, and a radar transceiver working at low level in the X-band. The antenna is constituted by a cylindrical horn and a dielectric lens. The transceiver is based on a specially adapted commercial low-cost module. The results obtained on the antenna base as well as those performed during actual working are presented.
