防步兵地雷地球物理探测技术国内外研究动态

战后遗留的数百万颗地雷在许多国家带来了严重的人道主义问题.其中防布兵地雷因为其体积小金属含量低,一旦被埋在地下将很难被发现,所以目前迫切需要研究和发展新颖的探测技术来消除目前国际社会十分关注的探雷问题.而高敏感度、高可靠度和低花费是对探测技术的基本要求.当前正在使用和发展的探测技术包括地球物理探测技术和非地球物理探测技术两大类.地球物理探测技术中,正在使用和有发展前景的探测技术主要包括:低频电磁感应、红外成像、核四极矩共振和探地雷达等技术.本文将主要介绍以上几种探测技术的原理、现状,并总结它们各自的优缺点.研究表明将几种探测技术有机地结合于一体的复合探雷器是解决地雷探测问题的一个不错的选择和当前发展的一个趋势.

Summarization of geophysical detection technologies for anti-personnel mines

Millions of landmines remaining from past conflicts have produced serious humanitarian problems.Antipersonnel(AP) landmines are big troubles for detection because of small size and low metal content.So to increase applied research of novel detection technologies is urgent in order to remove AP landmines.Sensitive,reliable and low cost sensors are the first and absolute requirement for the design of demining sensors.Currently landmine detection technologies consist of geophysical detection technologies and non-geophysical detection technologies.Geophysical detection technologies mainly include electromagnetic induction,infrared imaging,nuclear quadrupole resonace,and ground penetrating radar.This paper introduces the theory and application of these technologies,and summarizes their advangtages and disadvangtages.
