| Abstract: | The distributing features of the primary electromagnetic field and the secondary electromagnetic field in the frequency domain are analyzed. The theory to ascertain the underground iron pipeline by abnormal point of Hx, Hz is proposed and it is necessary to perform normal field-correction under the complex geologic condition. The efficiency of this method by case data of different type of pipeline is showed. |
