英文摘要	We study seismic data decomposition and reconstruction problems in this paper. Seismic data representation using sparse Gaussian beams is proposed. We formulate this problem as an l(0)-norm constrained minimisation problem. In solving the l(0)-norm minimisation, dip-angle scanning is performed and a quasi-Newton method is utilised to calculate the waveform function. Numerical experiments on synthetic data and real data indicate that the seismic data can be properly represented using sparse Gaussian beams with the sparse optimisation method. Moreover, the method has the ability to remove random noise and recover missing data. Finally, the waveform function obtained by sparse decomposition can be used for Gaussian beam migration. The approach described here can obtain a higher signal-to-noise ratio image than the traditional poststack Gaussian beam migration, and the overall runtime is comparable.
