DEVICE DESIGNED TO MONITOR LOCAL IRREGULARITIES AND GEODYNAMIC ZONES OF GEOLOGICAL SECTION TOP PART (GST) Russian patent published in 2009 - IPC G01V3/08 

FIELD: instrument making.

SUBSTANCE: invention relates geophysics, particularly, to electromagnetic LF devices intended for analysing GST. Proposed device comprises two antennas arranged orthogonally and connected to receiver, one of them being installed vertically. Proposed device comprises additionally data processing device and third antenna arranged orthogonally to aforesaid two antennas and connected to aforesaid receiver. The later incorporates transmitter with its output connected to the data processing device input. Transmitter allows transmitting signals comprising data on mutually-orthogonal components Hx, Hy, Hz of natural pulsed electromagnetic Earth field to data processing device the later allows computation of Wzx (x, y)=Hz/Hx and Wzy (x, y)=Hz/Hy, determination of relationship Wzx=F(Δf) and Wzy=F(Δf), where "ДГ" is the range of received frequencies of mutually-orthogonal components Hx, Hy, Hz, from f₀ to f and integration of aforesaid relationships Wzx and Wzy.

EFFECT: expanded performances, higher accuracy.
