Compact millimeter-wave distance and speed measurement sensor for railway applications

Radar sensor for use in automatic shunting system which executes remote control of track occupancy on hump yards and railroad switches and cut speed control passing along retarder position is developed. The sensors are equipped by systems of remote control and internal parameters diagnostics transmitting the radar and service information to the control point. The sensors could be applicable for use in the data nets. The main feature of the developed radar is the use of FMCW self-mixing transceiver with internal detection and digital control and spectral processing of the signal.
