Interferometric OBC Surface Related Multiple Attenuation

Flexible surface multiple attenuation using the curvelet transform

In this paper, we demonstrate that better primary preservation and effective surface multiple attenuation can be achieved by applying various iterative surface multiple attenuation approaches in different domains and in different areas. In areas where smaller moveout separation between primary and multiple exist, a conservative least-squares adaptive subtraction method is used to preserve prima...

Multiple scattering attenuation and anisotropy of ultrasonic surface waves

Multiple scattering of waves induces bulk effects such as attenuation and anisotropy that are important in seismology, optics, medical imaging, and other fields involving propagation in disordered media. We report here measurements of ultrasonic surface wave propagation in a strong-scattering, quasiperiodic medium consisting of a grooved surface of aluminum. Using noncontacting optical methods ...
