| Abstract: | It is proved in this paper that the phase data of electromagnetism responding under certain condition is not affected by the stochastic electromagnetism noise in theory. A method to computing the appearance resistivity by using phase data is also introduced. Compared with the remote reference data, it is demonstrated that the aberrant-field measured appearance resistivity data can be partly recovered and corrected by using the phase data. |
| Keywords: | Electromagnetism noise robust method trend analysis remote reference phase appearance resistivity |
