A new system and method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried objects. The method is useful in situations where clear isolated diffraction hyperbolas indicate the presence of an underground object, but the object's dimensions and filling may be unknown. The present invention acquires GPR data and applies advanced numerical methods to get the depth and size of the underground object in a very accurate manner. An embodiment of the invention includes five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.

Precise infrastructure mapping using full-waveform inversion of ground penetrating radar signals

A new method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried pipes. The method is useful in situation where clear isolated diffraction hyperbolas indicate the presence of a pipe, but pipe dimensions and filling may be unknown. The invention is a method of taking GPR data and applying advanced numerical methods to get the depth and size of an underground pipe in a very accurate manner. An embodiment of the method consists of five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.
