Abstract

Based on the analysis of the data files from the MTU series instruments, this study explored the data files from the Aether magnetotelluric system. The C# programming language was employed to write a program to decode the original time series A24 files, magnetic probe calibration apial files, and standard time series atts files, completing the development of time series split, read/write, and display modules, probe file read/write and display modules, and Fourier transform and Fourier coefficient display modules. Finally, the applicability of the program used in this study was tested by comparing the above modules with the relevant modules in the prMT processing software. The operability of the program was tested using actual field data. Overall, this study provides a certain basis and reference for delving into power spectrum estimation and interference signal processing.

Key words： magnetotelluric Aether data format C#
