【摘要】：針對磁偶極子模型提出了基于磁性目標磁梯度張量矩陣的特征值和特征向量的定向和定位方法。該方法以磁梯度張量信息作為磁測信息,以測量坐標系下的測量點坐標作為輔助信息,先通過單點梯度張量解得位置方向矢量,包括虛解和正解,再結合多點方向和輔助信息確定正解從而實現(xiàn)定位。在高信噪比情況下的仿真和實驗結果表明,該方法與直接反演法的定位效果相當,說明了該方法的可行性。
[Abstract]:A method of orientation and location based on the eigenvalue and eigenvector of magnetic gradient Zhang Liang matrix of magnetic target is proposed for the magnetic dipole model. In this method, the magnetic gradient Zhang Liang information is used as the magnetic measurement information, and the measuring point coordinate in the measuring coordinate system is taken as the auxiliary information. Firstly, the position direction vector is obtained by the single point gradient Zhang Liang solution, including the virtual solution and the positive solution. Then the forward solution is determined by combining the multi-point direction and the auxiliary information to realize the location. The simulation and experimental results in the case of high signal-to-noise ratio show that the localization effect of this method is comparable to that of direct inversion method, which shows the feasibility of the method.
