Overcoming Spatial Aliasing in Reflection Seismology
, by Shuki Ronen
I propose a method of overcoming spatial aliasing in two steps:
(1) Pre-stack: Dip moveout with zero traces between data traces.
(2) Post-stack: A correction applied in the frequency domain.
The derivation of this method is based on pre-stack partial migration and on the Fourier analysis of sampling and aliasing.
