| 英文摘要 | In this paper, we consider continuous solution methods for migration deconvolution imaging in seismic inverse problems. Direct migration methods, using the adjoint operator L*, usually yield a lower resolution or blurred image. Linearized migration deconvolution requires solving a least-squares migration (LSM) problem. However, we notice that the direct LSM method is unstable in computation which is a severe obstacle for visual explanation. We study regularized mathematical model. We first formulate the problem by incorporating regularizing constraints, and then employ iterative gradient methods for migration deconvolution and imaging. A hybrid gradient technique for ill-posed migration in verse problem is proposed. To show the potential for application of the proposed method, we use synthetic one-, two- and three-dimensional seismograms for seismic migration inversion. Numerical performance indicates that the proposed method is very promising for practical seismic migration imaging. |
