磁偶极极化率张量是一种具有关于大小、形状和材料的信息的对象特定属性。这种信息可被排雷行动中常用的电磁感应传感器用来区分埋在地下的地雷和杂物，从而降低误报率，提高排雷的吞吐量和安全性。本文介绍了一种能够获得小型金属物体和低金属杀伤人员地雷替代物的光谱张量的方法。实验结果验证模拟和解析解，以确保所获得的张量真实地代表绝对对象张量。绝对张量的一些典型的杂波项目和地雷的代理人，与地雷和杂波之间观察到显着的差异。
The magnetic dipole polarizability tensor is an object-specific property possessing information about the size, shape, and material. This information could be used by electromagnetic induction sensors typically used for demining operations to discriminate between buried mines and clutter, reducing false alarm rates, and improving demining throughput and safety. This paper presents a methodology capable of obtaining the spectroscopic tensors of small metallic objects and low metal anti-personnel mine surrogates. The experimental results are validated against simulated and analytical solutions to ensure that the obtained tensor truly represents the absolute object tensor. Absolute tensors for a number of typical clutter items and mine surrogates are presented, with significant variance observed between those of mine and clutter.
