Least-squares one-way wave-equation migration with matrix-decomposition propagation and sparse denoising regularization

Conventional one-way wave-equation migration methods often suffer from phase errors, amplitude distortions, and low-amplitude artifacts in the presence of strong lateral velocity variations, complex structures, and noisy data. To address these problems, we propose a sparse-denoising-constrained least-squares one-way wa...
