Study on MT data processing and denoising in southern Hunan

Abstract The magnetotelluric method is a geophysical method that uses natural electromagnetic field sources to explore deep geoelectric structures. However, with the development of the economy and the generalization of human interference, the signals collected in the field are susceptible to various noise interferences. This article intends to use the current Some denoising methods process the actual collected interfered signals to obtain robust impedance estimation results.
