摘要

As research conducted by US State Department, Landmines maim or kill an estimated five hundred people per week worldwide. Direct casualties are not the only problem. The areas of arable land cannot be farmed due to the threat of landmines. According to the United Nations, in 64 countries around the world, there are an estimated 110 million land mines still actively lodged in the ground. Landmines can be metallic or non-metallic types. The metal detectors can easily detect metallic types, which are buried close to the ground surface, however the ones, which are buried deep in the soil, cannot be detected by the metal detectors. The landmines which are non- metallic types (Plastics, Low metal containing landmines) also has a high probability that metal detector could not discriminate. For metallic types and non- metallic types, the probability of false alarm is very high. In this paper, we propose High Resolution Signal Processing Method using SAR algorithm which is based on migration techniques for the detection and discrimination of antipersonnel landmines using Impulse GPR. The Signal Processing Algorithm makes use of the High resolution GPR data from Landmine Detecting Array Radar (LAMDAR-III) to give the better imaging of the buried object.
