Abstract
Many countries in the world are suffered from buried landmines, remaining after various kinds of wars and conflicts. In order to save these courtiers and the people living there, technical contributions of scientists and engineers are required. Ground Penetrating Radar (GPR) is a very effective landmine detection sensor, and many tests have been carried out in order to deploy the technique in the Demining operation. In this paper, we first summarize the current technology of GPR and related signal processing, and then we introduce our research activities on application of GPR to humanitarian Demining. We developed two dual sensor systems for demining, namely ALIS and SAR-GPR. ALIS is a hand held GPR system and it has a visualization function of GPR. ALIS was tested by local deminers in Afghanistan. SAR-GPR is a GPR system equipped with an array antenna and a compact vector network analyzer. It is a very adaptive system and can select operation frequency depending on the soil condition, and high clutter reduction can be achieved using signal processing.
