压缩感知理论下基于快速不动点连续算法的地震数据重建
Seismic data reconstruction using FFPC algorithm based on compressive sensing
摘要
Abstract
Due to the limitations in acquisition conditions,seismic exploration data is usually incomplete and thus influences subse-quent seismic data processing.In this paper,a Fast Fixed Point Continuation (FFPC)algorithm based on compressive sensing theo-ry is used to reconstruct missing seismic data.First,wavelet transform is applied to seismic data.Then,the appropriate measure-ment matrix is selected through analysis of missing signal.Finally,an FFPC algorithm is used to reconstruct the missing seismic data.Tests on both synthetic data and field data show that the method could reconstruct missing seismic data with a high SNR.The FFPC algorithm is less time consuming and more efficient compared to the Fixed Point Continuation (FPC)algorithm.The FFPC algorithm also has a higher reconstruction precision compared to the traditional Orthogonal Matching Pursuit (OMP)and Spectral Projected-gradient for L1 minimization (SPGL1)algorithms.关键词
