  • 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.
