A New Approach for Adaptive GPR Diffraction Focusing

Several researchers have utilized multipath summation to manage the common problem of scattered energy within GPR sections. Such results in degrading lateral resolution and continuity reflectors. If detailed velocity models are known, then it is fairly easy focus by means conventional migration methods. However, this rarely case sections, as common-offset antenna array mostly used, therefore cannot provide models. This gives an important advantage for method, which has proved be successful focusing such diffractions, without need build a field model. method based on stacking (summation) constant migrated sections (weighted or not) over predefined range. The main drawback technique high computational cost user interference select appropriate weights. We developed improved implementation weighted that reduces both cost, weights selections. data adaptive methodology can expedite process, suppress model, reduce subjectivity. Moreover, spectral scaling scheme was developed. applied output process expected blurriness resulting
