High SNR Gaussian Beam Migration Based on Matching Pursuit Sparse Decomposition

Summary Matching pursuit is a technique of signal sparse decomposition, which is often used for time-frequency analysis and denoising processing. Gaussian beam migration (GBM) is an efficient and robust depth imaging method, which not only retains the advantage of ray-based migration, such as flexibility, efficiency and adaptability to the irregular topography, but also has a comparable imaging accuracy to wave equation migration. In this
