Seismic applications of the Radon transform and a new second-order traveltime local transform
- Author / Creator

Radon transforms play an essential role in seismic data processing. They have been
extensively used to separate signals from coherent noise, reconstruct seismic data,
and estimate the arrival direction of waves impinging on arrays. This thesis focuses
on applying Radon transforms to seismic signal processing, including multiple
suppression, denoising and seismic data regularization.
After reviewing classical Radon transforms that operate on the full aperture of a seismic
gather, I propose a new local Radon transform parameterized by two adjustable
parameters. The proposed Radon transform is derived using a second-order Taylor
approximation of the re
ection traveltime around a central seismogram. The proposed
local Radon transform enables processing data composed of a superposition
of complex waveforms with spatially variant dips.
