摘要
文章研究利用磁通感应技术对运动目标进行探测的方法。通过分析运动目标的磁特性,建立等效磁性模型。根据模型设计了探测感应线圈的结构,并从理论上推导出线圈内磁通量和感生电动势的求解公式。利用数值仿真获得了探测信号与运动目标特征及线圈参数的关系。计算结果表明,探测信号对运动目标参数及探测感应线圈的结构变化响应明显,初步验证了该探测技术的可行性。
In this paper, a method for moving target detection based on the magnetic flux induction is studied. Anequivalent magnetic model is built based on the target’s characteristics. According to the model, the structure of theinduction coil is designed. To obtain the relationship between the detected signal and the target features, a theoreticalderivation of the detectable signal is made. The response relationship of the moving target’s features and the coil parametersagainst the detectable signal is obtained through numerical simulations. The results show that the detectable signal isobviously affected by the moving features of the target and the structure of the coil, which validates in a preliminary stagethat the detection technology is feasible.
