摘要
根据台劳级数展开式,将窗口内网格结点位场数据在计算点展开,且对应点两两相减,由最小二乘法求得窗口内网格结点的水平导数算子,将此算子与观测的位场数据褶积,就可求得位场的水平导数。
Potential field data at gridpoints of a window can be expanded at calculation points by Taylor series expansion formula. Then, the data at a gridpoint will be subtracted from that at a corresponding point. A horizontal derivative operator for gridpoints in the window can be calculated by the least square method. This operator is convoluted with the observed potential field data to obtain the horizontal derivative of the potential field.
