The 13 pages that link to Ground-penetrating radar, each with the reason it gives.

• Remote sensingCompared with: It shares remote, noncontact measurement but targets subsurface features rather than surface mapping.

• RadarBroader topic: It adapts radar reflections to locate buried objects and underground boundaries.

• Seismic reflectionCompared with: It also uses echoes, but electromagnetic waves replace seismic waves.

• PermittivityRelated: Subsurface permittivity contrasts help determine radar-wave speed and reflections.

• SinkholeRelated: Radar surveys can detect some shallow voids and disturbed layers near sinkhole sites.

• Electrical resistivity tomographyCompared with: It images contrasts in electromagnetic properties using radar pulses rather than injected direct current.

• Unexploded ordnanceRelated: It can complement metal detection when locating buried explosive hazards.

• Glacier monitoringCompared with: It estimates ice thickness beneath the surface, which surface imagery cannot reveal.

• Relative permittivityRelated: Subsurface permittivity contrasts influence wave speed and reflected signals.

• Exploration geophysicsBroader topic: Its short-range imaging resolves shallow targets that deeper exploration methods may miss.

• Forensic geophysicsRelated: Radar reflections can reveal grave cuts, buried objects, and disturbed soil.

• History of radarRelated: Radar principles were adapted to locate buried features without excavation.

• Near-surface geophysicsRelated: Radar reflections locate interfaces and objects where ground conditions permit signal penetration.
