Abstract :
The detection of obstacles on railway level-crossings is usually ensured by small radars utilizing gunn diodes or similar devices. This process is not quite safe however and it may happen that a vehicle at standstill on the railway track cannot be detected. We are studying surface wave propagation, guided by the rails using transistor transmitters at lower frequencies.
