Summary:
Parabolic radon filtering is a widely used method to eliminate multiples. With the development of 3D acquisition system, 3D seismic data processing can obtain affluent underground information and increase resolution. However, actual marine seismic data usually mix up large multiples and traditional high-resolution method can’t get an ideal result. In this paper, we proposed a de-aliased high-resolution radon transform method to eliminate multiple of seismic data. In our method, we also take AVO effect of seismic data into account. In order to keep AVO effect, we use orthogonal polynomials to fit seismic data. Numerical examples illustrate that our method can get a high-resolution result with preserved amplitude.
