  • Compressive sensing and sparse reconstruction techniques are adopted to solve many
    seismic data processing problems, including the design of high-resolution transforms
    for coherent noise removal, signal separation, and seismic wave eld reconstruction.
    Traditional sparse reconstruction algorithms optimally work with noise-free data or
    data contaminated with random noise of Gaussian distribution. Their performance
    degrades in the presence of erratic noise. In this thesis, erratic noise refers to
    noise characterized by large and isolated amplitudes. The thesis proposes robust
    sparse reconstruction algorithms that are resistant to erratic noise. These algorithms
    are adopted to solve the simultaneous-source separation problem via robust sparse
    Radon transforms.
