GPR-signal improvement using a Synthetic Emitter Array

► The Synthetic Emitter Array improves typical GPR reflection signals. ► The SEA signals are clearer than the Single Offset (SO) and CMP signals. ► Time and amplitude fluctuations decrease with SEA and signal to noise ratio increases. ► The SEA method is useful to make visible very weak reflections and diffractions. ► The SEA method aids visualizing apparently discontinuous strata and edges of surfaces.
