Abstract

Electromagnetic scanning is a new high-resolution technology for the investigation of a nearsurface layer down to depths of a few tens of metres using a controlled electromagnetic radiation at the frequency interval from 1 kHz to 5 MHz. Over this range the distribution of electromagnetic energy is of diffusive-wave character which is very promissing for solving a wide scope of problems. Using the fundamental frequency lower that of georadars the proposed approach has no limitations connected with increased electrical conductance of a medium and depends less on near-surface inhomogeneities. Particular features of the method consist in high density of the spatial-temporal recording of the field; the possibility to study real conductive media; obtaining the distribution of electrophysical features and object positions by spatial-temporal projections.
