| 摘 要： | 详细讨论了STRATAGEM(EH4)音频大地电磁测量系统资料处理过程中所隐含的重要步骤及其实现过程,特别是由时间序列资料经FFT变换后所产生的原始谱叠加后的频点与其相应的X文件(互功率谱文件)中的频点对应、归属与筛选问题,由X文件形成Z(阻抗)文件时X文件中频点与Z文件中频点的对应、归属与筛选问题。上述问题的解决,为相关研究人员利用该设备所采集资料而开发其他阻抗估算技术提供了基础。

| Abstract: | The key steps and performance in the data process of STRAGEM（EH4）system was discussed in details,especially the raw cross-powers caused by the time-serial data＇s FFT,its stack and the corresponding problems in the X file（the cross-power file）such as frequency reflecting,attribution and sifting,as well as those between X file and Z file（impedance file）.The solution to the above problems can provide a basis for the related researcher to develop new impedance estimation technique for the EH4＇s time-serial data. |
