摘要
以天津宝坻新台FHD-2B质子矢量磁力仪为例,分析了其运行质量和干扰情况.从观测数据的连续率和有效率,观测数据背景噪声和数据一致性,数据变化动态及主要干扰等方面进行了分析研究.结果表明:宝坻新台地磁FHD观测数据的连续性和有效率较高;仪器背景噪声较大,高于全台网噪声平均值;在日常观测中,主要受到高压直流输电、地磁暴和主机故障等干扰.研究结果对同类台站同类仪器数据分析应用具有借鉴意义.
Abstract
Taking Tianjin Baodi New Terrace FHD-2B proton vector magnetometer as an example,the instru-ment observation principles and performance indicators are introduced,and the operation quality and interfer-ence are analyzed.This article conducts analysis and research from observation data continuity and effective-ness,observation of data background noise and data consistency,data change dynamics and main interfer-ence.The results of the study show that the continuity and efficiency of the observation data of the Geopagnetic FHD observation of the new platform;the instrument has a large background noise,which is higher than the average of the full-scale network noise;in daily observation,it is mainly subject to high-voltage DC trans-mission,geomagnetic storms,and host failures.Interference.Provide reference for the analysis of similar in-struments of similar stations.
