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. © 2011 Elsevier B.V.
