    en.wikipedia.org/wiki/Ground-penetrating_radar

    Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [ 1 ]

  3. Demining - Wikipedia

    en.wikipedia.org/wiki/Demining

    Ground-penetrating radar (GPR) probes the ground using radar. A GPR device emits radio waves; these waves are reflected at discontinuities in permittivity and one or more antennae pick up the return signal. The signal is analyzed to determine the shapes and locations of the reflectors.

    en.wikipedia.org/wiki/RIMFAX

    The Radar Imager for Mars' subsurface experiment (RIMFAX) is a ground-penetrating radar on NASA's Perseverance rover, part of the Mars 2020 mission. It uses radar waves to see geologic features under the surface. The device can make detections dozens of meters/yards underneath ground, such as for buried sand dunes or lava feature. [1]
