Incomplete Data Production Techniques in GPR Research and Applications

Abstract

GPR data are used for analyzing, processing, visualization and interpretation of the underground archeological and other structures. The accuracy of underground structures depends on the completeness of GPR data collected from search area. Due to some search area properties such as uneven surface, presence of archeological and other structures on the surface, etc. collected data become incomplete and inadequate. Another problem is related to the size of search area. Collecting the data with small profile intervals from large search area is costly and time-consuming. In order to contribute to solve these problems this work proposes an approach to produce incomplete GPR data and new profiles with small intervals. Proposed approach consists of three stages. At the first stages, incomplete data and new profiles are produced on the base of original profiles using standard and proposed nonstandard interpolation techniques. At the second stages, produced profiles are compared with original GPR profiles. Finally, at the third stage, the most effective interpolation techniques are defined. Obtained results showed that the proposed interpolation techniques increase the accuracy of underground structures.
