It pioneered the all-directional forward and inverse methods of magnetic anomalies in the three directions and directions in magnetic prospecting. First of all, in the spherical coordinate system, a general forward expression of two spherical harmonic series of graded magnetic anomalies in three directions and directions is deduced, which lays a theoretical foundation for the realization of omni-directional inversion. Then, based on the first gradient anomaly spherical harmonic series expression, the third-direction total magnetization direction and the magnetic moment mode inversion method are proposed. Based on the expression of the second gradient magnetic anomalous sphere harmonic series number, Third-dimensional body magnetic moment center of gravity, approximate shape and distribution range, as well as a wide range of practical value of the “average magnetic convex body” boundary point position and other omni-directional inversion method. Finally, an example of theoretical model verification of omnidirectional inversion of a three-dimensional body gradient magnetic anomaly is given.
