METHOD FOR VOLUMETRIC RECONSTRUCTION OF ELECTROPHYSICAL MODEL OF SUBSURFACE MEDIUM USING UNMANNED ELECTROMAGNETIC SYSTEM Russian patent published in 2025 - IPC G01V3/16 

FIELD: measuring.

SUBSTANCE: invention relates to aerial exploration of minerals using magnetic fields varied by an object. Multi-view unmanned electromagnetic system for volumetric reconstruction of an electrophysical model of a subsurface medium comprises an electromagnetic field source and signal receivers. Electromagnetic field source is made in the form of an inductor, which is a generator loop and a current switch, which forms in the inductor a sequence of probing current pulses with amplitude and duration of current and pause specified in the switch. Signal receivers are made in the form of receiving antennae and signal recorders with the possibility of detecting the primary electromagnetic field of the inductor and eddy currents secondary induced in the geological environment. Electromagnetic field source and each of the signal receivers are mounted on unmanned aerial vehicles (UAV), one per source and each of the receivers. UAVs of electromagnetic field source and signal receivers are made with possibility of joint and simultaneous synchronous flight. Signal receivers are located in the same echelon with a vertical offset relative to the electromagnetic field source and lateral relative to each other, at which the signal from the medium is at least 10 % of the absolute value of the inductor forward field signal.

EFFECT: enabling volumetric reconstruction of an electrophysical model of a subsurface medium using an unmanned electromagnetic system.
