How far can ground radar detect? This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km). Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
Can GPR penetrate concrete? Ground-penetrating radar can be used on rock, soil, ice, fresh water, pavements, and structures—concrete or otherwise. (It is less effective on some very electrically conductive media, such as saltwater and most clays.)
What can GPR detect? GPR is safe for use in public spaces and a wide variety of project sites. It detects metal and non-metal objects, as well as voids and underground irregularities.
