Stable and efficient Q-compensated least-squares migration with compressive sensing, sparsity-promoting, and preconditioning

X Chai, S Wang, G Tang, X Meng - Journal of Applied Geophysics, 2017 - Elsevier
The anelastic effects of subsurface media decrease the amplitude and distort the phase of
propagating wave. These effects, also referred to as the earth's Q filtering effects, diminish …
