Transient Electromagnetic Signal Filtering Method Based on Intelligent Optimized Time-Space Fractional-Order Diffusion Equation
To filter out noise in transient electromagnetic (TEM) signals, a Time-Space Fractional-order Diffusion Model (TSFDM) based on intelligent optimization is proposed.Firstly, based on the characteristics of the TEM signal, the signal is subjected to dynamic threshold segmentation processing.Then, the discrete difference method and the Grunwald-Letnik
