Ground-penetrating radar, or GPR, is a means of exploring the shallow subsurface with electromagnetic waves (radar), usually in the 10 to 1000 MHz band. The two-way traveltimes of reflected radar waves give the depths where changes in electrical properties occur. Also called georadar, ground probing radar, and surface penetrating radar.
