UWB-Based Positioning System for Supporting Lightweight Handheld Ground-Penetrating Radar

Abstract

The paper presents a concept of a high-accuracy positioning system, using ultrawideband (UWB) radio modules. The system is dedicated for supporting operation of a handheld ground-penetrating radar (GPR), as the use of information about the antenna coordinates at the moments of scanning enables correction of the radar signals and facilitates creation of high-resolution subsurface images. The presented system is self-contained and easy-deployable; it has centimeter-level accuracy and provides positioning data with high repeatability. The system’s structure, mathematical model, positioning algorithm and chosen simulation results are presented in the paper.
