基于预条件共轭梯度法的盲源反褶积方法(英文)
Blind Deconvolution Method Based on Precondition Conjugate Gradients
【摘要】 在勘探地震学的数据处理过程中,盲源反褶积是一项重要的技术。本文给出了盲源反褶积方法的一种具体实现,并结合Krylov子空间上优化的预条件共轭梯度法以改善算法的稳定性,同时减少计算量。
【Abstract】 In seismic data processing, blind deconvolution is a key technology. Introduced in this paper is a flow of one kind of blind deconvolution. The optimal precondition conjugate gradients (PCG) in Kyrlov subspace is also used to improve the stability of the algorithm. The computation amount is greatly decreased.
