Ground Penetrating Radar
GPR has many common uses in modern society, specifically in the archaeological and geological fields. Some police and government agencies even use ground penetrating radar for buried body locating.
Ground penetrating radar was invented in the 1970's and it's initial purpose was to detect land mines for military soldiers. After those in the construction industry realized it's benefit for certain applications, GPR quickly became used on an every day basis.
Southern Radar Imaging uses the technology to perform routine bridge assessments which helps local government officials stay up-to-date on the reliability of local bridge structures, as well as underground utility location to make sure no water pipes, electrical lines and cables, or gas lines are struck and damaged during construction. Ground penetrating radar can also be used to locate rebar and post tension cables in concrete slabs and walls.

How landmines are detected
Portable Landmine Detection System : DigInfo
DigInfo - http://movie.diginfo.tv Developed by Tohoku University Professor Motoyuki Sato's group, the Advanced Landmine Imaging System, or ALIS, is a portable landmine detection system which combines a ground penetrating radar and a metal detector to produce images of objects detected underground. A typical antipersonnel land mine is about 10cm in diameter and about 4cm in thickness. On a conventional landmine disposition site, landmines are found as rarely as one out of 1,000 metallic responses. However, ALIS's sensor scans a ground surface and sends sensor signals in realtime to the small portable display that shows an image of an object detected underground. Since the display clearly shows the image of a buried mine, mine detection operations can be much more efficiently conducted compared to conventional operations that depend on reflected sounds. The ALIS combines a conventional metal detector and a high-performance ground penetrating radar we developed. The ALIS is unique in that it contains in the main unit that I carry a compact radar and a battery that lasts half a day for monitoring. Another unique thing is this small display. People involved in disposing landmines can observe how a landmine is buried in realtime. We already had the ALIS evaluated in Afghanistan and Cambodia in a long-term experiment. ALIS uses a portable vector network analyzer the group developed with Anritsu, which makes it possible to learn about how deep the mine is buried by analyzing the 3D underground structure around the mine. Professor Sato wants to apply ALIS as an underground measuring technology to securing and managing infrastructures such as gas and water pipes as well as underground water and other environmental issues.
