Abstract

An algorithm is proposed for constructing metrological approximations of potential fields of the Earth and planets using local and regional versions of the modified S-approximation method. Depending on the available a priori information about the fields and their sources, the main parameters of the method are selected in automatic and semiautomatic modes. Equivalent source distributions are found with respect to the external field, resulting in images of orebodies “from different angles,” making it possible to estimate the depth of mass carriers or magnetic moments. The results of a mathematical experiment on locating prismatic bodies based on gravity field values at points within a certain observation network are presented.
