摘要: 在黄小晶等人提出的混合相位未知脉冲反褶积方法[1,2]基础上,本文提出一种改进的反褶积方法。与文献[2]的反褶积方法比较,本方法具有运算量小,压缩地震子波的反褶积效果更好等优点。

Abstract:

Based on an unknown mixed-phase pulse deconvolution proposed by Huang Xiaojing,an improved deconvolution method is presented in this paper. Compared with Huang s decomvolution,this method possesses the advantages of (1)less operation and (2)a better deconvolution effect for the seismic wavelet compression.
