矢量磁场和磁场全张量数据是多磁源反演的数据基础。针对矢量磁场和磁场全张量的测量问题，文章提出了矩阵式矢量磁场连续扫描方法。对利用矢量磁场计算磁场全张量所用的数据结构进行了研究，应用MATLAB软件对常用的十字形和六面体两种不同数据计算结构进行了仿真分析，结果表明，两种计算结构的误差相近且均不大于10%；并分析了基线距离对磁场全张量计算的影响，结果表明，磁场全张量计算误差随着基线距离的增加而增加。

The data of the vector magnetic field and the magnetic full tensor are the foundation of the multi-magnetic source inversion. For the measurement of the vector magnetic field and the magnetic full tensor, a sequential scan method in the matrix mode is proposed. Two data structures, the crisscross structure and the hexahedron structure, for the computation of the magnetic full tensor through the magnetic field are used in the MATLAB simulations. It is shown that the results obtained by using the two data structures are very close with differences less than 10%. The influence of the baseline length on the results of the magnetic full tensor is analyzed, and the influence is shown to be great and it increases with the increase of the dateline length.
