METHOD FOR PROBING SUB-SURFACE SPACE USING WAVE SIGNALS (OPTIONS) Russian patent published in 2024 - IPC G01S13/89 G01V1/28 G01V3/12 

FIELD: geophysical surveys.

SUBSTANCE: invention relates to geophysical surveys for the purpose of identifying and localizing geological structures and subsurface objects. The first version of the method for probing subsurface space using signals of a wave nature includes generating a probing signal, recording the signal reflected from the subsurface section of the media, followed by processing the results and determining parameters for calculating the position of the point of reflection of the probing signal from the section of the media. The transmitting device generating the probing signal and three receiving devices that record the signal reflected from the subsurface section of the media are placed at the vertices of a rectangle conditionally formed on the surface or above the surface of the geological space under study with the center at the physical point being examined. The distance to the point of separation of the media from the surface from which the research is carried out is determined based on the reflected signals received by all three receiving devices simultaneously, as the height of a conventional straight pyramid, the base of which is a rectangle, conventionally formed by the transmitting and three receiving devices located at its vertices. When calculating the height of the pyramid, the length of each of the edges of this pyramid is determined as half the product of the speed of propagation and the probing signal and the time interval between the time of generation of the probing signal and the time of recording its reflection from the media section in the subsurface space by each of the three devices receiving its reflection. In the second embodiment of the method, one receiving device is alternately installed in each of the three vertices of a conditional rectangle. In this case, the probing signal is generated each time after installing the receiving device at the next vertex of the rectangle.

EFFECT: increasing the efficiency of geophysical surveys.
