An innovative time-depth conversion for the management of buried scenarios with strong discontinuities

Abstract

This paper proposes a time-depth conversion accounting for discontinuities of the investigated buried scenario, which reverse in discontinuities of the propagation velocity of the waves. The focus is on the imaging of cavities in the framework of GPR prospecting. We show that a time-depth conversion accounting for the different propagation velocity of the waves in the cavity and in the surrounding soil can significantly improve the imaging in an easy way. Both simulated and experimental results will be proposed.
