METHOD FOR GEODYNAMIC MONITORING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC G01V3/08 

FIELD: geophysical research.

SUBSTANCE: invention relates to the field of geophysical research; it can be used in systems for geodynamic monitoring for control of changes in inner structures of geological media. A method for geodynamic monitoring consists in supply of probing signals to point sources, and reception of signals from several pairs of point meters. At the same time, methods for modulation and expansion of spectra are used for a pair of probing signals shifted by a phase to a set angle relatively to each other and coming to two point sources, between which pairs of point meters are located along the circumference. Dynamics of changes in phases of registered signals of pairs of point meters relatively to a phase of reference highly stable oscillation is controlled. The measuring device for geodynamic monitoring contains sequentially connected differential amplifier, the first amplifier with a variable amplification coefficient, a phase detector, a lower frequency filter, an amplifier, a device for conversion of a signal into a degree measure. A signal from a reference generator, passing through the second amplifier with a variable amplification coefficient, comes to the second input of the phase detector.

EFFECT: increase in noise immunity and sensitivity in registration and detection of small geodynamic events.
