Abstract
This paper examines the full-waveform inversion method in the image domain. A theoretical and numerical analysis of solutions of the inverse dynamic seismic problem in the image domain is performed using asymptotic methods. A Gaussian beam migration operator is used for transformation to the image domain. A theoretical and numerical comparison of reflection tomography and the developed asymptotic full-wave inversion method is presented. A connection is established between the operators of linearized problems of tomography on reflected waves and asymptotic full-waveform inversion in the image domain. Numerical experiments have shown that reflection tomography is effective for reconstructing low-frequency models, while asymptotic full-waveform inversion in the image domain ensures the restoration of details of complex medium structures, with computation speeds being approximately equal for both methods.
