Brief communication: Monitoring active layer dynamics using a lightweight nimble ground-penetrating radar system – a laboratory analogue test case

Abstract. Monitoring active layer dynamics is critical for improving the understanding of near-surface thermal and hydrological processes in cryosphere. This study presents laboratory test a low-cost ground-penetrating radar (GPR) system within experiment freezing thawing monitoring. The an in-house-built low-power monostatic GPR antenna coupled with reflectometer piloted by single-board computer (SBC) was tested prior to field deployment. correspondence between frozen front electromagnetic (EM) reflection temperature allowed us ability closely monitor bottom reflection.
