Abstract

We present a technique to eliminate the surface waves by an interferometry-nonlinear local filter (NLF). This technique consists of 3 steps: i) remove the surface waves by the NLF; ii) predict the residual surface waves and primaries by the interferometric method; iii) predict the surface waves by the NLF and remove the residual surface waves by a matched filter. Field data tests, for both 2D and 3D surveys, show that this technique effectively mitigates surface waves and preserves much of the reflection information.
