Seismic inverse scattering by reverse time migration
Seminar Room 1, Newton Institute
AbstractWe will consider the linearized inverse scattering problem from seismic imaging. While the first reverse time migration algorithms were developed some thirty years ago, they have only recently become popular for practical applications. We will analyze a modification of the reverse time migration algorithm that turns it into a method for linearized inversion, in the sense of a parametrix. This is proven using tools from microlocal analysis. We will also discuss the limitations of the method and show some numerical results.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
