Abstract :
More than 60 courtiers are still suffered from land mines. ALIS is a hand-held dual-sensor developed for humanitarian demining, which has been developed at Tohoku University, Japan since 2002. The dual-sensor ALIS is equipped with a metal detector and a GPR (Ground Penetrating Radar). A unique and novel sensor tracking system, which can record the GPR and Metal detector signal with their acquired locations, is equipped in ALIS. Due to its sensor location information, we can reconstruct buried land mine images in 3D space after data acquisition. IN addition, we found that the image reconstruction or migration processing drastically increases the quality of the image of the buried objects. ALIS evaluation test was conducted in Croatia in October 2007. Then a half-year evaluation test of ALIS in QC test in Croatia was held during December 2007 and April 2008. In this test, we could obtain fruitful experience in various soil and environmental conditions in Croatia.
