摘要
在对电场拓扑理论研究的基础上,将拓扑公式中原记录点与加密点的两个拓扑公式合并成一个公式,通过研究大地电磁时间域数据格式,利用VC++语言编写软件,实现了大地电磁时间域数据的拓扑计算。对实测CEMAP数据进行了拓扑处理,计算结果表明,拓扑处理实现了判别与压制静态效应,通过与空间滤波处理结果对比表明,拓扑处理去静态方法是可行的,且效果优于空间滤波处理。软件界面简单,布局合理,运行高效,处理快速。
Based on the electric field topological theory,this paper merges two separate topological formulas of original record points and pass points.Then,we realize topological calculation of MT time-domain data by developing software with Visual C＋＋ after studying the MT time-domain data format.The calculation results of topological processing of observed CEMAP data suggest that this kind of processing successfully distinguish and suppress the static effects.The static correction method based on topological processing is reliable,and the obtained effect is better than that after spatial filtering after comparing topological processing and spatial filtering.This software runs efficiently and processes data fastly with a simlpe interface and a reasonable layout.
