Abstract
The paper considers the problem of identifying the relationship between the parameters of a conductive object and EMF signals. Models of a localized object in a half-space and an object covered by a conductive layer are investigated. As a result of three-dimensional mathematical modeling, EMF signals in time are obtained for various models of the environment and the position of the object. The distributions of abnormal signals according to the calculated EMF are constructed. A method for estimating the parameters of an object based on the revealed dependencies of abnormal signals on the position of the object and its induction mass is proposed. The characteristic dependences applicable for rapid assessment of body parameters without three-dimensional inversion are revealed. The results demonstrate the possibility of estimating the depth of the upper edge of the target object and its induction mass by measuring anomalies in EMF signals. However, to improve the accuracy of estimates, it is necessary to take into account the time required for the field to propagate in the upper layer.
