Figure 2 Top, left: original GPR
data. Top, right: Enhanced Random Noise Attenuation result. Bottom, left:
fx decon result. Bottom, right: tx decon
result. The encircled area has fewer artifacts in the ERNA
result. Differences between panels are much more visible when viewed electronically.

Figure 3 Top, left: original prestack seismic
data. Top, right: Enhanced Random Noise Attenuation result. Bottom, left:
fx decon result. Bottom, right: tx decon
result. In the ERNA result, the upper encircled area has fewer
artifacts, and the lower encircled area shows more continous
reflectors (less ``checkerboard'' noise). Differences between panels are much more visible when viewed electronically.

Figure 4 Top, left: original poststack seismic
data. Top, right: Enhanced Random Noise Attenuation result. Bottom, left:
fx decon result. Bottom, right: tx decon
result. The encircled area at the bottom of the figure shows more continous
reflectors (less ``checkerboard'' noise). Differences between panels are much more visible when viewed electronically.

Figure 5 Final ERNA residuals and the RMS values of
successive residuals, normalized with respect to the input data
(shown as iteration 0 with a RMS of 1). Top panels: GPR. Middle
panels: Seismic prestack. Bottom panels: Seismic poststack.
