Typical Interference Analysis of FHD-2B Observation Data at Wujiazhai
Combing the influence of all kinds of interferences on the instrument is helpful to identify precursor anomalies better,and eliminating interferences can improve the quality of data observation.In this paper,the typical interference factors of FHD-2B instrument in Wujiazhai are classified and analyzed from the aspects of ferromagnetic material and electromagnetic activity interference,and the solution to the response is given.The results show that the interference of ferromagnetic material to FHD-2B instrument in Wujiazhai is factory operation,vehicle interference,man-made interference,infrastructure project interference,etc.,electromagnetic interference is High-voltage direct current#Back to back interference and subway operation interference.
