CA 2180609
A wheel detector for indicating the presence of a rail vehicle on a set of spaced rails is disclosed. The wheel detector transmits a radar pulse signal and samples a portion of the signal corresponding to a target area on one of the rails. The wheel detector will generate an indication signal if a change in the reflectivity of the received signal corresponding to the target area is detected. The wheel detector may additionally include multiple transmitters and receivers to provide redundancy, and be configured to determine the linear velocity and direction of a wheel.
