Application of the Attribute Analysis for Interpretation of GPR Survey Data

An investigation of extended road surfaces with artificial pavement, as well as of railways, airfield runways and monolithic concrete structures when searching for defects, cracks and voids in the pavement, or locating weakness zones in high humidity areas and sub-base subsidences. The application of an Attribute Analysis for interpreting data obtained while Ground Penetrating Radar (GPR) surveying allows one to isolate anomaly zones of a given section with much less effort. The attributes offered allow one to undertake an analysis of amplitude and frequency parameters, as well as of the parameters associated with the attenuation of an electromagnetic field in the temporal and frequency domains. The Attribute Analysis boosts the quality of GPR data, simplifies finding the location of fractured zones in artificial structures, easily locates high humidity areas, ground compaction and possible voids under the hard surface of engineering structures with extended areas, and visually provides data in a simple to grasp form.
