METHOD OF CONSTRUCTING GRAVITATIONAL FIELD TRANSFORMANT Russian patent published in 2011 - IPC G01V7/06 

FIELD: physics.

SUBSTANCE: multilevel gravitational field analytical model is constructed in form of an approximation structure from point sources. Additional information on the gravitational field used is data on the topography of the observation surface and data on anomalous gravitational field on the working surface and the bordering region from materials of different-scale investigations. Coefficients (mass) in equations for given functions of coordinates of point sources are determined such that the analytical model field coincides with the given measured field with the required accuracy. Further, gravitational field transformants are calculated by applying various transformation operators of the sourcewise function to all equations of point sources in the approximation structure followed by additive superimposing of the calculated transformant levels. The multilevel gravitational field model meant for calculating the transformant has dimensions which are greater than the area of analysis.

EFFECT: high reliability of accounting for the effect of side sources, accurate values of any derivatives of anomalous gravitational potential can be obtained with minimum expenses.
