Guofeng Feng, Bo Han, Jiaqi Liu · Chinese Journal of Geophysics · 2003
Abstract Combining the widely convergent homotopy method applied to the inversion process of operator identification with the Tikhonov regularization method for ill‐posed problem, a new Widely Convergent Generalized Pulse‐Spectrum Technique (WCGPST) for 2‐D wave equation inversion is constructed. And constraint inversion is preformed with data of well logs. Many numerical simulations and tests of anti‐noise indicate that this method is effective.
