基于低秩Hankel矩阵分解的地震数据重建
Reconstruction of Seismic Data based on Low-rank Hankel Matrix Decomposition
摘要
Abstract
Reconstruction of seismic data is necessary due to physical and economic constraints and noise contamination,which makes seismic signal data missing,which will affect the subsequent processing and interpretation of seismic data.The low-rank and Hankel matrices are combined to reconstruct the random missing seismic data:a fast low-rank Hankel matrix decomposition method is used to perform the 2D reconstruction directly in the time domain,which decomposes the nuclear norm term substitution into the sum of the two matrices,avoiding the SVD computation,and accelerating the computation speed.In the solution,the alternating direction multiplier method is used for alternating iterative processing to further speed up the computation.Both synthetic data and actual seismic data tests verify the effectiveness of the method.Moreover,the method is superior to the f-k domain filtered reconstruction method in terms of reconstruction accuracy and signal-to-noise ratio.关键词
