| | Abstract | | A rigorous full waveform inversion of wavefield data has been a challenging subject, partly because of the lack of precise knowledge of the source. Recently full waveform inversion algorithm for ground-penetrating radar, GPR, has been developed and applied to field data. Since conventional approaches involve some form of approximations to the source, inversion results are subject to the quality and the choice of the source information used. We present full-waveform inversion methodology for GPR tomography which is independent of source waveform uncertainty. The algorithm minimizes misfits of GPR interferograms which are generated by deconvolving or cross-correlating observed wavefields at different receiver locations. This approach is demonstrated using a simple two-dimensional problem, suggesting the independence of this method from source uncertainty. |
