GPR antenna array for the inspection of railway ballast
- A GPR antenna array was investigated for automated measurement of wave propagation velocity as a measure of the ballast quality. This goes beyond the regular application of conventional radar systems offering only qualitative structural information. The new approach provides a fast NDT method for the classification of ballast fouling. A main advantage of the multi-offset radar is that regular ballast digging for velocity evaluation can be avoided and travel time can be directly transformed into an equivalent depth by using the automatically evaluated velocity. Fast monitoring of ballast fouling condition can reduce maintenance cost significantly by supporting the works necessary for ballast cleaning and furthermore this method reduces interruption time for a better railway service.
