Outline of Final Research Achievements

The research projects aimed at developing evaluation methods of metal detectors and GPR used and being used for landmine clearance operations.
The quality of GPR data degrades when soil permittivity exhibits spatial variation. In order to investigate the influence GPR responses are modelled with various soil heterogeneities. It was found and demonstrated that at specific frequencies the influence of spatial pattern becomes greater. Furthermore, an analytical method to calculate metal detector response for soils from magnetic susceptibility. Using the method soils can be characterised based on the expected metal detector performance for the detection of buried objects. In addition a method for measuring dielectric and magnetic properties of soils was developed.
