Abstract: The eddy-current probe (EC-probe) RBF-metamodel is constructed, which can be used to eddy-current density calculate at control points of the space located in the control zone object surface, in the tasks of the EC-probe synthesis. As a coil of excitation of the EC-probe surface, an alternating current actuator, located above the control object with a constant specific electrical conductivity and magnetic penetration, was used in the work. The informatively model's verification was carried out by calculating the correlation coefficient multiplicity and verifying its statistical significance. When planning a multifactorial experiment, for the obtaining regression models purpose, LPτ-sequences were used, which proved to be promising for the surrogate optimization problems solution. The proposed computing technology has allowed developing an informative and adequate metamodel of the overhead EC-probe, which can be effectively used in optimal surrogate synthesis problems.
