Summary
Our inventors have developed a method for full-waveform inversion (FWI) of common-offset ground penetrating radar (GPR) data, particularly targeting the dimensions and infilling material of buried objects. We have met this long-standing need by applying state-of-the-art FWI that can estimate object size, position, inner and outer dimensions and determine the in-filling material properties (water, air, natural gas etc.). The technique can improve an initial guess of the pipe diameter to a better estimate with less than 8% misfit for pipes with inner diameters ranging from 3 to 90 centimeters and buried with a top depth of 35 centimeters. Our researchers have successfully employed this method on a number of real datasets collected in different environments. It demonstrated accurate location and depth estimation on multiple buried objects and noisy media. This method will be invaluable to industries and government agencies engaging in construction, infrastructure monitoring and quality assessment and excavation near utilities.
