Multiple attenuation using a high-resolution time-domain Radon Transform

Zhihong Cao and John C. Bancroft

ABSTRACT

A high-resolution time-domain Radon transform is used to identify and separate multiple energy from seismic reflection energy. The transform used is an optimized semblance-weighted Radon transform. In this method, the highest energy trajectories are identified first in the Radon domain, then the energy is subtracted immediately from the source gather before it is used by other trajectories. This process improves the spatial resolution of the energy in the Radon domain.

The high-resolution time-domain Radon transform was applied to real and synthetic data and produced encouraging results.
