Ka-band FMCW radar sensor for remote control of presence and speed of railroad-cars and trains in territory of grading belts

The results of development of low cost radar sensors for remote control of track occupancy and railway cars speed over the territory of hump yards under heavy weather conditions are presented. The radar sensor feature is application of Ka-band FMCW autodyne (self-mixing) transmitter and digital systems for forming sounding signal and spectral processing of received signals. Sensor is equipped with the systems of remote control and transmission of radar and service information to the control point.
