METHOD OF MEASUREMENT OF ELECTROMAGNETIC FIELD GROUND WITH MINERAL strong absorption FIELD GEOLOGICAL ENVIRONMENT IN CONDITIONS OF STRONG INTERFERENCE

摘要

Method terrestrial measuring the electromagnetic field subsoil with a large absorption of rock and strong interference from remote sources, comprising the steps of: generating a difference signal from two antennas made up of the same horizontally lying on the ground surface spaced antenna framework, characterized in that in order to ground measurement of the electromagnetic field in subsurface geological strongly absorbing medium, one of the antennas is provided with the magnetic core, transporting the magnetic field at the surface and subsurface serving simultaneously mage itnym antenna core formed of a steel well casing, determine the change in the transfer function of the antenna caused by the influence of a magnetic core eliminates the influence of the difference of transmission antennas functions on the signals received signals received by antennas used for generating the difference signal, and the magnitude of the difference signal is judged on the electromagnetic subsoil field.
