LASER SECONDARY RADAR FOR AUTOMATIC COLLISION AVOIDANCE

The use of radar to aid in collision avoidance in modern railroad systems is considered. Taking into account the security requirements and the fact that each train can be provided without problems with the required equipment, the advantages of a secondary radar are evident. One has further the choice between microwaves and laser frequencies. The use of the laser results in very sharp defined radiation patterns without unwanted sidelobes, even for small antenna dimensions. A compact laser secondary radar for automatic collision avoidance in underground railroads or similar railroad traffic systems is presented.
