processing amultifold ground penetration radar data using common-diffraction-surface stack method

Recently, the non-destructive methods have become of interest to the scientists in various fields. one of these method is ground penetration radar (gpr), which can provide a valuable information from underground structures in a friendly environment and cost-effective way. to increase the signal-to-noise (s/n) ratio of the gpr data, multi-fold acquisition is performed, and the common-mid-points (cmps) are acquired. compared to the traditional cmp method, which is applied to a cmp, the common-reflection-surface (crs) method is introduced for seismic data processing considering the neighboring cmps. in addition, instead of a point on the reflector, crs assumes that the reflector is part of a circle. with these two characteristics, crs produces a stack section with a high s/n ratio. the common-diffraction-surface (cds) method, which is a simplified version of crs, enhances the diffractors related to the underground anomalies like pipeline, flume, and caves. we apply the cds stack method on a multi-fold gpr data and compare it to the crs results. these results show that the cds method can provide a high s/n ratio stack section compared to the traditional cmp method.
