Development of ALIS and the evaluation tests in Afghanistan and Egypt

摘要

ALIS (Advanced Landmine imaging system) is a hand-held sensor system composed of a ground penetrating radar (GPR) and metal detector (MD) for landmine detection. Also ALIS has a sensor position tracking system that make ALIS can offer the visualized information. For the signal processing of GPR data set, 3D diffraction stacking migration is used to enhance the signal-clutter ratio for effective image reconstruction. Continuous variable root-mean-square (CV-RMS) velocity was used to adapt migration to various depths of target. The evaluation test of ALIS was held in December 2004 in Afghanistan and in May 2005 in Egypt. ALIS had good performance at both sites and some results on these tests are reported.
