Abstract

The results of experimental studies to detect and locate subsurface hidden objects by near-surface determination of statistical variations of the natural pulsed electromagnetic background field in the 0.1-50 kHz frequency range are presented. There are possibilities of passive electromagnetic probing by use of the necessary electronic equipment and statistical signal processing technique described. Some field results to locate subsurface pipelines and cables and other hidden objects including archeological ones are shown. The perspectives of this passive probing technique for variety of applications in urban conditions are discussed.
