- Аннотация: The method of signal registration implemented in GPRs using frequency or time gating or nonlinear amplification of amplitudes may significantly impact the view of the waveforms, in fact, distorting the reactions of rocks to the applied electromagnetic field of the probing signal. This distortion of the field occurs under various experimental conditions and may affect the ability to draw reliable inferences about rock characteristics if it is not taken into account when interpreting the GPR data. Numerically calculated waveforms obtained in the approximation of geometric optics or significant simplifications of the models of propagation of electromagnetic signals cannot serve as a standard in GPR and be directly applied to a wide range of experimental results obtained by different GPRs, which differ in design. We describe some of the typical effects of the GPR design on waveforms and some interpretational errors, which occur when the effect of the registration technology implemented in the receiver is not taken into account.
