A study of the EM method to explore strata
Wang You, Chuan Wei · Chinese Journal of Geophysics · 2006
In order to apply the basic principle of a new EM method of exploration to practice and to provide some bases for developing equipment, the following three problems are analyzed and discussed: When the source signal is a sharp electromagnetic pulse,the output waveforms of the second_order band_pass filter of incident wave and reflected waves; the inversion method by using the waveform of transient superposition of incident waveform_front and reflected waveform_fronts to get electric conductivity and thickness of strata; and the key problem in the design of sounding equipment. The result shows that the solution is still unique and application to practice is possible.
