摘要
安全、准确又快速地探测金属未爆炸物是一个全球安全治理难题。磁法是当前未爆炸物探测的一个主要手段,超导量子干涉器(SQUID)作为新兴的磁探测设备具有巨大潜力。SQUID磁梯度的基本特点是灵敏度极高、噪声低,在弱磁场探测领域发挥重要作用。作者提出将SQUID应用于金属未爆炸物探测领域的方法,通过SQUID磁梯度仪样机对未爆炸物模型的测量实验和仿真计算,得出其测量结果准确可靠且反演结果与实验设置吻合,初步验证了SQUID应用于金属未爆炸物探测领域的可行性和研究价值。
To detect metal unexploded ordnance(UXO) safely,accurately and rapidly is a global security management challenge.Magnetic method is one major methods to detect UXO,and superconducting quantum interference device(SQUID) is an potential and emerging magnetic detection device.The general features of SQUID are high sensitivity,low noise.SQUID plays an important role in weak magnetic detection.An UXO detecting method is presented based on SQUID magnetic gradient detector.A UXO detection experiment by SQUID and a simulation detection are porformed.The result preliminarily proved the accuracy and reliability of SQUID’s measurement and inversion,and the feasibility and research value of application of SQUID in UXO detection.
