【摘要】：针对磁偶极子模型提出了基于磁性目标磁梯度张量矩阵的特征值和特征向量的定向和定位方法。该方法以磁梯度张量信息作为磁测信息,以测量坐标系下的测量点坐标作为辅助信息,先通过单点梯度张量解得位置方向矢量,包括虚解和正解,再结合多点方向和辅助信息确定正解从而实现定位。在高信噪比情况下的仿真和实验结果表明,该方法与直接反演法的定位效果相当,说明了该方法的可行性。
[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.
