ANISOTROPIC DIFFUSION AND REMOVE OF THE STATIC EFFECT IN ELECTROMAGNETIC SOUNDINGS

摘要：

The influences of non-homogeneous body of the shallow earth and terrain cause distortion of the observed resistivity sounding curve and affect the following integrated interpretation in frequency domain electromagnetic soundings. Anisotropic diffusion is smoothing method based on the difference of gradient magnitude of diffusion point, and given the different diffusion coefficient, the method not only can effectively remove noise, but also protect the feature information. In this paper, the anisotropic diffusion is introduced to the processing of influences of shallow non-homogeneous body and terrain in the frequency domain electromagnetic soundings. The test results show that the method is characteristic of survey section.
