Some effects of the background removal of interest in archaeologicalGPR prospecting

摘要

This contribution deals with the effect of the background removal procedure on GPR data for an inverse scatteringalgorithm funded on the Born Approximation in the simple case of a scalar two-dimensional geometry. The effect isexamined with regard to both the problem of the extraction of scattered field data from the total field data and to theperformances of the reconstruction approach. As it will be shown, the background removal amounts to a spatial filteringof the available reconstruction and, depending on the kind of target looked for, it can be very useful but also quite uselessor even harmful.
