METHOD FOR REMOTE SEARCHING OF UNDERGROUND COMMUNICATIONS LOCATION AND DETERMINATION OF THEIR LATERAL DIMENSION AND OCCURRENCE DEPTH IN THE GROUND Russian patent published in 2018 - IPC G01V3/16 G01V3/17 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring technology and can be used for remote location of underground communications (pipelines, cables, etc.), their transverse size and depth in the ground. They form a swarm of unmanned aerial vehicles (UAVs) connected to each other and the central control station by communication channels. Through the communication channels they control the flight path of the UAV, the relative position of the UAV and the height of the UAV flight above the ground. On several UAVs, they place transmitters with sending antennas. On each of the other UAVs they place receivers with receiving antennas for receiving electromagnetic field components. With UAV with a transmitter and a transmitting antenna 4, a primary electromagnetic field is generated. On the receiving UAVs with the help of receivers with receiving antennas they get the signals of the primary electromagnetic field and the secondary final electromagnetic field created by the interaction of the primary field with the underground conducting objects over which the UAV swarm moves. Data of the UAV coordinates and the signals of the electromagnetic field components received by the receivers are transmitted to the central control station through communication channels. Based on the results of the joint processing of the received signals the electromagnetic field components and UAV coordinates data they determine the location of underground communications, their transverse size and occurrence depth in the ground. During the search, the UAVs in the swarm can be reconfigured under control from the central control station, changing the direction, speed, altitude and relative position of the UAV in the swarm to ensure optimum search conditions and flight safety.

EFFECT: wider field of use.
