FEASIBILITY STUDY FOR RAILROAD EMBANKMENT EVALUATION WITH RADAR MEASUREMENTS

A study was conducted to determine the feasibility of using radar measurements to define railroad embankment subsurface layer thickness and properties. A computer model was used to calculate radar reflectances as could be measured over the frequency range of 0.5 to 2.0 GHz at the surface of five different railroad embankments for which data were available. These reflectance curves were converted to realistic depth displays as could be obtained from a realtime analysis of swept-frequency radar data or from a more conventional narrow-pulse radar system. Comparisons were then made of the results of the radar system measurements with the physical conditions of the embankments.
