摘要:

应用离散富氏变换(DFT)的反褶积方法,与计算反褶积的Z变换和最小平方法相比,具有以下优点:(1)精度高。(2)运算量少。(3)对地震子波无相位要求。

关键词: 反褶积, 离散富氏变换, 误差分析, 运算量

Abstract:

A method of deconvolution with discrete Fourier transform is discussed in this paper. Compared with other methods of deconvolution (Z transform method and least square method),this method has three advantages:
1 .High precision;
2 .Less operations;
3. No supposition that the seismic wavelet is minimum phase.

Key words: Deconvolution, Discrete Fourier transform, Error, Operation
