{wiki=Ground-penetrating_radar}
Ground-penetrating radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface. It operates by emitting high-frequency electromagnetic waves into the ground and measuring the reflected signals that bounce back from subsurface structures or layers. GPR is widely used in various fields, including: 1. **Archaeology**: To detect and map artifacts, structures, and other archaeological features without excavation.
