Abstract
Summary
We suggest a new method for the Laplace domain full waveform inversion (FWI) which use single damping constant. This method makes the Laplace domain FWI more efficient, because the proposed method uses only one damping constant during inversion process. To scale the gradient direction properly, we use simple depth window function to steepest descent direction. We demonstrate that the algorithm is working by numerical test using synthetic data set.
