FIELD: measurement equipment.
SUBSTANCE: invention applies to the field of radiolocation, partly to the method for control of ballast layer condition in railway track. Method for detection of ballast layer contamination in railway track consists in analysis of electromagnetic field coming from contaminated ballast layer and processing of its quantitative characteristics. Measurement of quantitative characteristics of signals in SHF-range is registered by receiving antenna of georadar. Signal amplitude is exposed to numerical processing on computer and is compared to calibration dependencies.
EFFECT: improved quality of railway track ballast layer examination.
