- W4210839094 abstract "Aiming to the problem that Full-waveform inversion (FWI) easily plunges into local optimum, an effective multiscale FWI method is proposed for subsurface penetrating radar (SPR) in time domain. The method decomposes observed signals to different scales for inversion by utilizing a frequency selection method and Wiener low-pass filters. In addition, limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) and iteration step determined by Wolfe condition-based line search are employed to solve the inversion optimization problem for improving inversion efficiency. Synthetic experiment indicates the proposed method can effectively improve the inversion effect." @default.
