| 摘 要： | 针对海洋磁力测量数据处理中面临的磁扰期间的日变改正问题,基于傅立叶级数建立了日变数据处理谐波分析模型;通过应用于大批量实测日变数据处理,确定了谐波截断次数,实现了日变基值、平静日变改正和磁扰改正的合理分离。

| Abstract: | For diurnal correction problems during magnetic disturbance in marine magnetic survey dataprocessing,the harmonic analytic models are derived on the basis of Fourier series.Using a set of practice surveydata,the maximum harmonic degree is defined.The harmonic coefficients,diurnal base,peaceful diurnalcorrection and geomagnetic disturbance confluence are all calculated by the method and benefit to identify thediurnal base,the peaceful diurnal change and magnetic disturbance. |
