A HIGH RESOLUTION ELECTROMAGNETIC METHOD OF EARTH FOR REMOVING STATIC FREQUENCY DOMAIN

摘要

A high resolution electromagnetic method of earth for removing static frequency domain includes that many sampling devices are provided at zone to be explored and a common electrode point for adjacent survey points shares the same electrode; the results of observing each path extending along the same direction are conventionally disposed respectively to obtain a conventional observing curve, and solve a sequence of electric field component of topology point and encrpytion topology point; the electric field component is treated as an observing field value, and a power spectral analysis is performed and an impedance tensor is estimated. The change curve of resistance-polar distance for single frequency point of the same recording spot is plotted, and the change rule of resistivity is observed and analyzed, then the static interferential value of resistance is edited and deleted, and a value of resistivity for the frequency point is solved.
