The authors are developing innovative sensor systems for humanitarian demining. A hand held dual sensor ALIS (Advanced Landmine Imaging System) is one of them, which is a combination of a GPR (Ground Penetrating Radar) sensor and a metal detector. ALIS uses metal detector as a primary sensor for metal objects, and then use GPR for confirmation for burie dlansmines. With a wide frequency (1 GHz - 4 GHz) operation of the system and sophisticated signal processing, ALIS can image buried landmine under strong clutter conditions. SAR (synthetic aperture radar) signal processing is the msot important for clutter reduction. The authors have evaluated the ALIS system in some mine affected courtiers including Afghanistan, Croatia and Cambodia. ALIS evaluation test was conducted in Cambodia in 2006, where ALIS was operated by local deminers. They could show that ALIS can discriminate landmines and metal fragments.
