Abstract
A method for collecting and processing the tensor artificial-source electromagnetic signal data and a device thereof; the method comprising the steps of: step S1: determining an electric field polarization direction in a measuring area, and arranging electromagnetic field sensors according to the electric field polarization direction in the measuring area, step S2: respectively collecting artificial-source electromagnetic field signals and natural-field-source electromagnetic field signals, step S3: respectively Fourier-transforming the collected electromagnetic field signals, thereby obtaining the electromagnetic field values corresponding to the artificial source, and the collected electromagnetic field signals corresponding to n groups of natural sources, step S4: calculating to obtain the underground tensor impedances according to the electromagnetic field values corresponding to the artificial source and the electromagnetic field signals corresponding to n groups of natural sources that are obtained based on the least square method, step S5.
