Detection of metallic and plastic landmines using the GPR and 2-D resistivity techniques

Low and non-metallic landmines are one of the most difficult subsurface targets to be detected using several geophysical techniques. Ground penetrating radar (GPR) performance at different field sites shows great success in detecting metallic landmines. However significant limitations are taking pla...
