Subsurface imaging by UWB radar: Application to humanitarian demining in Cambodia

Research output: Contribution to journalReview articlepeer-review


Ground Penetrating Radar (GPR) has been widely used applications which include detection of subsurface facilities, concrete inspection and archaeology. Among these applications, humanitarian demining is still difficult task. Since 2002, we have developed a new hand-held land mine detection dual-sensor ALIS. ALIS is equipped with a metal detector and a GPR, and it has a sensor tracking system, which can record the GPR and Metal detector signal with its location. ALIS can process the data and is used for image re-construction by migration processing. ALIS is the only one mine detection system in the world which can visualize the GPR image by hand scanning. We found that the migration processing can reduce the clutter and gives us clear images of buried mines. After several tests of ALIS in mine affected courtiers, operation of ALIS in mine fields in Cambodia started in summer 2009. Two sets of ALIS have been operated in Cambodia and more than 77 antipersonnel mines have been detected and 137,000m 2 farmland was cleaned.
