A robust x-t domain deghosting method for various source/receiver configurations

Here we present a method of robust seismic data deghosting for marine broadband seismic data processing. We extend the time invariant method presented by Yilmaz et al (2015) to include time varying ghost generating system parameter estimation and deghosting. This extension enables the utilization of this method in x-t domain. The applicability of a deghosting method in x-t domain not only has advantages in being able to pick more precise ghost generating system parameters, but also enables extension of the method readily to 3D. Additionally, this extension allows us to utilize this method in a variety of acquisition geometries, including slanted cable, dual cable/dual source, vertical cable etc. We demonstrate the effectiveness of the time varying ghost generating system parameter estimation method on a real data example with comparisons to the original timeinvariant estimation and deghosting.
