Zusammenfassung |
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 place in the case of low and non-metallic landmines. Electrical
resistivity imaging (ERI) technique is tested to be an alternative or
confirmation technique for detecting the metallic and non-metallic landmines
in suspicious cleared areas. The electrical resistivity responses using
forward modeling for metallic and non-metallic landmines buried in dry and
wet environments utilizing the common electrode configurations have been
achieved. Roughly all the utilized electrode arrays can establish the buried
metallic and plastic mines correctly in dry and wet soil. The accuracy
differs from one array to the other based on the relative resistivity
contrast to the host soil and the subsurface distribution of current and
potential lines as well as the amplitude of the noises in the data. The ERI
technique proved to be fast and effective tool for detecting the
non-metallic mines especially in the conductive environment whereas the
performances of the other metal detector (MD) and GPR techniques show great
limitation. |
