ABSTRACT:
A method for removing a static frequency domain, by (1) installing multiple sampling devices; (2) performing conventional processing whereby obtaining conventional observation curves; (3) adding electric-filed components of two adjacent observation points, those of three adjacent observation points, and adding electric field components of up to n adjacent observation points whereby obtaining electric fields of different polar distance, i.e. a sequence of electric field components of topology points; (4) using the sequence of the electric field components and the encrypted topology points sequence as an observation field value to perform power spectrum analysis and impedance tensor estimate; (5) drawing a resistance-variation of polar distance curve of a single frequency point of the record point; observing and analyzing a variation rule of resistivity, editing and deleting static interference resistance; and (6) repeating the previous step to complete edition of all frequency points of all record points.
