Analysis on Geomagnetic Data of Yingcheng Station Based on Fast Fourier Transform
Abstract The time-frequency analysis of geomagnetic observation data of Yingcheng seismic monitoring station since 2018 is carried out by using fast Fourier transform, and the frequency domain characteristics of geomagnetic data are obtained, which provides information for identifying interference factors in daily geomagnetic data processing, and has guiding significance for improving the quality of geomagnetic observation data.
Key words :
geomagnetic observation
