On passive detection of underground bodies by using the natural electromagnetic pulsed radiation

© Polishchuk V.I.

Passive detection of conductive (cables, various pipelines) and nonconductive (drains, water - bearing channels, cavities, liquid escapes from pipe-lines, etc.) underground objects by correlation coefficients anomalous changes of natural Earth's pulsed electromagnetic field flow density is proposed. The experimental outcomes of such objects detection at the depth up to 13 m by radiowave indicator of stressed - strained rock state are presented.
