New method for denoising borehole transient electromagnetic data with discrete wavelet transform
2019
Journal of Applied Geophysics
Discrete wavelet transform (DWT) has been widely used as a useful tool in denoising geophysical data for its outstanding feature of detecting singularities and transients. In this paper, we develop a new strategy of denoising borehole transient electromagnetic (BHTEM) data. The principle idea of the denoising process is keeping those coefficients which are necessary to reconstruct the signal unchanged and setting others to zero. In our case, according to results of modeling, only the first
