Abstract
Summary
Many theoretical papers show the potential of the crosshole GPR full-waveform inversion, however to apply the full-waveform inversion to experimental data is still challenging. We have applied the crosshole GPR full-waveform inversion to many different datasets in Germany, Switzerland and USA. Here, we will give an overview of all the important steps and developments of the full-waveform inversion during the last years that are necessary for a successful application to experimental GPR data. Thereby, we will discuss important pre-processing steps including time zero correction, source wavelet estimation and different inversion strategies.
