Abstract: Due to the growing need to improve the accuracy of GPR studies for detecting anomalies and monitoring underground mine workings, the relevance of using modern data interpolation methods becomes especially important. This study analyzes and compares different interpolation methods, in particular identifying the advantages of the cubic interpolation method, to optimize the processing of GPR measurements. During the work, various interpolation methods were considered and applied, including linear and polynomial interpolation, as well as splines, in order to evaluate their accuracy and applicability to GPR data. Particular attention is paid to the cubic interpolation method, which was applied to real GPR data to evaluate its effectiveness in reconstructing a complete picture from incomplete or sparse data. The results of the study demonstrated that the cubic interpolation method provides significant improvements in the accuracy of GPR studies, allowing for more effective detection of anomalies and prevention of potential hazards. The cubic method was found to be able to more accurately recover missing data areas, making it the preferred choice for GPR specialists. The study confirmed the high applicability and efficiency of the cubic interpolation method in GPR data processing, providing valuable recommendations for selecting the most suitable interpolation method to improve the accuracy and safety of GPR studies.
