| Abstract: | Geomagnetic observation data of Shandan Seismic Station has been subject to serious interference from geoelectrie observation, which leads to declining in the accuracy of geomagnetic observation data. In order to eliminate geoelectric interference, the paper takes advantage of Fourier transform. The results show that the method could eliminate this type of interference effectively. |
