Research on single point localization method of superconducting magnetic gradient tensordetection system

针对磁异常目标远距离定位的问题,本文提出了一种基于超导磁梯度张量探测系统的单点定位方法。通过测量观测点处的一阶磁梯度张量与磁总场强度即可实现对磁异常源的实时定位。仿真结果表明,探测距离为1000 m时,该定位方法的最大相对定位误差为5.27%。实验结果表明,探测距离为128 m时,该定位方法的最大相对定位误差为5.47%,可满足超导磁梯度张量探测系统远距离实时定位的需求。

To solve the problem of remote localization of magnetic anomaly source,a single point localization method based on superconducting magnetic gradient tensor detection system was proposed.The magnetic anomaly source could be located in real time by measuring the first order magnetic gradient tensor and the total magnetic field intensity at the observation point.The simulation results show that the maximum relative positioning error of this method is 5.27%when the detection distance is 1000 m.The experimental results show that the maximum relative positioning error of this method is 5.47%when the detection distance is 128 m,which can meet the requirement of remote real-time localization of the superconducting magnetic gradient tensor detection system.
