PRACTICAL EXPERIENCE OF USING OF THE SOFTWARE REALIZING ALGORITHM OF APPROXIMATION OF POTENTIAL FIELDS BY ANALYTICAL FUNCTION AND THE INVERSE SOLUTION

M.N. Markova, E.P. Lapina

Under rugged terrain a character of relief strongly influences on the observed data. There is in an initial field not only abnormal mass but also topography features of the analysis area are reflected. As a consequence of this, a result of qualitative analysis of field sources can contain errors. Proposed in this paper is a method of carrying out of qualitative analysis of the initial data using some set of transformants and analytical approximation of potential fields. All mathematical procedures are summarized. The software is created. Its efficiency is shown on two practical examples.

Keywords: qualitative analysis, analytical approximation, gravitational field, topography, minimization of a functional, method of subsidiary bodies, transformants.
