"Regularized inversion of full tensor magnetic gradient data"
Wang Y., Luk'yanenko D.V., and Yagola A.G.

Features of numerical solution of the three-dimensional ill-posed problem devoted to the inversion of full tensor magnetic gradient data are considered. This problem is simulated by a system of two three-dimensional Fredholm integral equations of the first kind. The Tikhonov regularization is applied to solve this ill-posed problem. The conjugate gradient method is used as a minimization method. The choice of the regularization parameter is realized according to the generalized residual principle with consideration of round-off errors capable of affecting the final result of calculations significantly.

Keywords: magnetostatics, full tensor magnetic gradient data, inverse problems, ill-posed problems, regularization method.
