Existing tomographic inversion techniques for crosshole georadar data are based on geometric ray theory. Such techniques only consider limited aspects of the recorded data, only account for firstorder wave propagation effects, and hence only resolve large‐scale components of the subsurface. In contrast, FDTD‐based waveform inversions of crosshole georadar account for all relevant wave propagation effects. The corresponding results demonstrate that our waveform inversion approach is capable of adequately resolving both the geometry and the parameter distribution of anomalies whose spatial extent is considerably smaller than a dominant wavelength.Permalink: https://doi.org/10.1190/1.2148249FiguresReferencesRelatedDetailsCited ByUnderground Cavity Detection Through Spectral Distortion of a GPR SignalIEEE Transactions on Geoscience and Remote Sensing, Vol. 60Model-based layer stripping FWI with a stepped inversion sequence for GPR data8 May 2019 | Geophysical Journal International, Vol. 218, No. 2Application of a new 2D time-domain full-waveform inversion scheme to crosshole radar dataJacques R.
