Combined migration results and time-depth conversions in two layered media

Abstract

In this contribution, we will expose a strategy for mitigating possible differences in the propagation velocity of the electromagnetic waves within a given Bscan. The idea is based on a combination of different migrated results achieved under different assumed values of the propagation velocity. In cases of practical interest, this can also allow an easy time domain conversion coherent with the detected differences of propagation velocity. In particular, here the case of a two layered soil will be considered.
