| Abstract: | With the tool software of Matlab interference signal is removed from the true variation of geomagnetism for carrying out FFT transformation, the geoelectricity Z and D components of geomagnetic measurements and is clearly displayed. The process promotes the analysis capability of geomagnetic data and improves the veracity of geomagnetic anomaly recognition and identification. It is useful for the analysis and investigation of geomagnetic data. |
