| 摘 要： | 对内蒙古自治区锡林浩特地震台2019年10-11月质子矢量磁力仪FHD-2B的数据进行常规分析，发现D分量测值数据出现噪声大、突跳多的异常现象。对该台质子矢量磁力仪受干扰数据进行傅里叶变换和小波分析，确定干扰源范围，排除外界干扰可能。进一步对仪器进行检测，确定干扰原因为参数漂移，在进行参数校正后，观测数据恢复正常。

| Abstract: | Routine analysis of the data of proton vector magnetometer FHD-2B from October to November 2019 at Xilinhot Seismic Station revealed that the D component measurement data was abnormal with large amplitude noise and a large number of sudden jumps. In this paper, Fourier transform and wavelet analysis are carried out on the interfered data of the proton vector magnetometer at the Xilinhot Seismic Station to determine the interference source range. The instrument was further tested to determine that the disturbance was caused by parameter drift. By calibrating the instrument parameters, the instrument observation data returned to normal. |
