Abstract
We
discuss improvements produced by a Synthetic Emitter Array on typical
GPR reflection signals. We analyze their time and amplitude fluctuations
and their intensity levels with respect to the surrounding signals. We
compare the results of the method to those of the more usual Common
Midpoint method, as well as the Single Offset results. We analyze
diffractions at small objects and reflections at large interfaces for
both simulated and real data. We evaluate the effects of different
fluctuation levels in the soil parameters and the setting of the
relative phases between the array components.
