APPLICATION FEATURES OF RADAR VELOCIMETERS FOR MOBILE RAILWAY OBJECTS
Having compared different speed measurement methods, the authors study the application features of Doppler radar velocimeters (DRV) in railway transport. DRV desired specifications are determined. The issues of using DRV in the control systems of mobile railway objects are discussed. The analysis is given to the radar characteristics of the railway objects and amplitude-frequency features of the echoed signal spectrum. An approach to calculation the efficiency of railway transportation involving Doppler velocimeters is demonstrated.
