Estimating the Effective Conductivity of the Underlying Surface Based on the Results of Receiving the Electromagnetic Fields in the Middle Zone of an Active Source in the Earth–Ionosphere Waveguide

Experimental studies of signals from a controlled source in the middle zone under various geophysical conditions have been performed. In the experiment, five field electromagnetic components were measured in the range 0.3–95 Hz. Based on these observations, the effective conductivity of the underlyi...

Description
Summary:Experimental studies of signals from a controlled source in the middle zone under various geophysical conditions have been performed. In the experiment, five field electromagnetic components were measured in the range 0.3–95 Hz. Based on these observations, the effective conductivity of the underlying surface was calculated and an interpretation of the results was given.
