dc.description.abstract | In geophysical prospecting and environmental monitoring, the frequency domain electromagnetic induction technique has been developed for measuring the apparent soil electrical conductivity. A linear model can be formulated to described the response of the EM38, a ground conductivity meter. To image the subsurface conductivity profile from recorded data, the model has been inverted defining a Least Squares problem with Tikhonov approach improves the conditioning of the resulting linear systems, profile reconstruction can be surprisingly far from the expected conductivity behaviour. | IT |
