Abstract:In simultaneous-shot full-waveform inversion (FWI), the re-started L-BFGS algorithm can be used to suppress crosstalk, but crosstalk cannot be completely eliminated from the inversion results. To further solve the crosstalk problem caused by the interference among individual shots in simultaneous-shot FWI, an adaptive structure-based smoothing is applied to the FWI with the re-started L-BFGS algorithm. The structure-based smoothing can mitigate the crosstalk by highlighting structure boundaries. To perform str… Show more
