Embodiment Construction
[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. to limit the present invention.
[0032] Firstly, the classical regularization inversion method is briefly reviewed, and then the multi-objective particle swarm inversion algorithm for magnetic data proposed by the present invention is described.
[0033] (1) Magnetic data regularization inversion method in the prior art
[0034] The regularized inversion of two-dimensional physical properties of magnetic data involves the forward calculation of regular grid cells, so it is necessary to discuss the forward calculation. Divide the underground half-space into regularly arranged two-dimensional prism elements, any prism element such as figure 1 shown. When the magnetization direction is consistent with the direction of the geomagnetic...
