摘要：

It is of great importance to de-noise signal processing or parameter estimation in the data processing of geophysics. In this paper, anisotropic diffusion (AD) is introduced to signal processing of electromagnetic field in geophysics, effectively remove the interference of noise and outliers to signal and impedance estimation of the proposed methods, restore the basic shape of the surveying signal and improve the accuracy of impedance estimation. Results of test show: the absolute average error of impedance estimation based on anisotropic diffusion (AD) is only 4.5%, those of Least square (LS) and Robust estimation are 18.4%, 4.9% respectively.
