Abstract:
In the article used to study possible applications for monitoring the integrity of the trains radar-Doppler method. The features of a radar-Doppler sensing space near the railway infrastructure including moving train. We prove the sufficiency of the statement of radar measurements to determine the integrity of the train. An algorithm of monitoring the integrity of a train according to the results of radar measurements and the structure of the pulse-Doppler radar control system for its implementation. The analysis of the topological characteristics of radar reflecting objects. The analysis of energy, time and frequency including the Doppler shift of the reflected radar signal parameters. Is made a rough calculation of the signal power at the input of the radar receiver for typical conditions the control of the train. The conclusions about: a) inclusion of the inlet tract of primary processing of the low noise amplifier; b) applying a secondary path signal processing filtering multi-channel matched, and of the received signals correlation analysis.
