GRADIOMETRIC METHOD OF MAGNETIC SURVEY AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01V3/00 

FIELD: measurement technology.

SUBSTANCE: group of inventions relates to magnetic measurements of spatial distribution of stationary parameters of geomagnetic field (GMF) and can be used both for mapping of stationary magnetic field of the Earth, and drawing maps of geological structures, which serve as a permanent base. Gradiometric method of magnetic survey of stationary geomagnetic field (GMF) induction parameters additionally includes stages, at which increment of induction parameters within primary converter boundaries is measured; calculating increment of induction parameters based on measurements; selecting points with extreme values of measured increments of induction parameters of GMF and calculating rate of increments of induction parameters between extreme values; calculating gradient of increment of induction parameters between points with extreme values of induction parameters of GMF; method includes restoring, by linear integration, the induction parameters of the stationary GFM between them; determining sizes and position of objects creating measured anomalies.

EFFECT: high accuracy and reliability of measuring objects.
