摘要
Data-processing plays an important role in the magnetotelluric(MT) sounding work.For several simultaneous sounding sites,in particular,it is required to process field data with magnetic remote reference,which is time-consuming and demands a huge amount of calculation.The professional processing software named SSMT-2000 is commonly used to carry out the work;nevertheless,because of the restriction of the software,the batch processing for data from several sites can’t be carried out efficiently.Hence dataprocessing has become a tedious and long time work for MT workers.In this paper,the authors analyzed the format and the calling pattern of parameter files,probed into the problem as to how the internal executables are called by SSMT-2000 and,on such a basis,developed a smart code based on the MATLAB language.The code has the utilities of running a batch processing for fast Fourier transform,Robust estimation of impedance tensors for one single site and utilization of magnetic remote reference technique in three ways.The authors can apply the code to process data from many MT sounding sites at one time,which makes multiple-site data processing procedures much simpler and more efficient.
