Landmine detection by 3D GPR system
2012
In order to demonstrate the possibility of Ground Penetrating Radar (GPR) for detection of small buried objects such as
landmine and UXO, conducted demonstration tests by using the 3DGPR system, which is a GPR system combined with
high accuracy positing system using a commercial laser positioning system (iGPS). iGPS can provide absolute and better
than centimetre precise x,y,z coordinates to multiple mine sensors at the same time. The developed " 3DGPR" system is
efficient and capable of high-resolution 3D shallow subsurface scanning of larger areas (25 m 2 to thousands of square
meters) with irregular topography . Field test by using a 500MHz GPR system equipped with 3DGPR system was
conducted. PMN-2 and Type-72 mine models have been buried at the depth of 5-20cm in sand. We could demonstrate
that the 3DGPR can visualize each of these buried land mines very clearly.
