用FFT消除地电观测对地磁数据的干扰
Eliminating geoelectric observation interference for geomagnetic data with FFT
【摘要】 山丹地震台地磁观测资料受到地电观测的严重干扰,造成地磁观测资料应用精度下降。本研究采用Fourier变化对地电干扰进行剔除。结果认为:该方法对处理此类干扰具有良好的效果。
【Abstract】 Geomagnetic observation data of Shandan Seismic Station has been subject to serious interference from geoelectric 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.
