Method of Signal Processing For Mother Earth Impedance measurement

摘要：

DFT method of magnetotelluric impedance measurement is put forward, which can accurately measure excitation signal and AC power one. Gaussian weighted window is used; twice DFT analysis can accurately measure each separated spectrum. The key point is the window spectrum of the chosen window function is narrow enough so that each separated spectrum can be considered isolated. The methods provide theoretical basis for designing device to accurately measure magnetotelluric impedance.
