Ground-penetrating radar, also known as GPR, is a method of mapping the subsurface of the ground. It is a non-destructive imaging method that uses electromagnetic radiation and detects the reflections from subsurface structures. It is used in a variety of industries and fields, including archaeology, underground exploration, and structure inspection.
