Results of electromagnetic sounding conducted using multi-frequency equipment at the geoelectric test site of the Institute of Petroleum Geology and Geophysics (Novosibirsk, IPGG SB RAS) are presented. The test site, constructed for studying resolution of geophysical equipment for electromagnetic measurements and improving the methodical base of field works, consists of ten 100 m2 squares with 33 inserted targets.

A study of real or imaginary components of the signal demonstrated that objects located at the depth over 1.5m are generally detected with the real component measurements, while objects at the depth of 0.5–1.5 m are detected more distinctly with the imaginary component measurements. Metal and other contrast objects at various depths and positions can create over three extremums on plots and maps, which leads to difficulties in interpreting this material.

The phase of differential signal distribution appears to be an efficient way to display the field data.

Keywords: frequency sounding, measuring approach, response interpretation, geophysical test site.
