FIELD: geophysics.
SUBSTANCE: method includes excitation of sine signal or series of counter-phase pulses with certain delay, receiving excited signal by two antennae with distance between them equal to result of multiplication of semi-period of excited signal or delay between pulses by speed of electromagnetic wave. One received signal is subtracted from another one. Difference signal is subjected to time-scale transformation and prior processing. Device has block of differential locator, containing transmitter, receivers, synchronization device and processing and registration channel. Outputs of receivers are given in counter-phase to inputs of synchronization device. Receipt antennae are positioned symmetrically relatively to transmitting line.
EFFECT: higher efficiency.
