Abstract

A novel combination model is proposed for the magnetic field generated by the complex structure of the vehicle, which consists of magnetic dipoles and magnetized cubes. Simulation experiments conducted on this model, in conjunction with measurements obtained using a SQUID gradiometer, validate its effectiveness. The results demonstrate a strong correlation between the simulation and experimental curves, thereby affirming the model’s applicability for precision detection of complex vehicles in non-line-of-sight scenarios.

车辆运动磁场组合模型

针对车辆由磁偶极子和磁化立方体组成的复杂结构所产生的磁场，提出了一种新的组合模型。在此模型上进行的模拟实验，结合使用SQUID梯度仪获得的测量结果，验证了其有效性。结果表明，仿真曲线与实验曲线具有较强的相关性，从而验证了该模型对非视距场景下复杂车辆的精确检测的适用性。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
