... data, and then recover it back. Figure 2 shows the reconstruction for data that has been randomly decimated by 50%. Notice that in this case, one does no require to use the anti-alias algorithm of Naghizadeh and Sacchi (2013), because random sampling inhibits aliasing. Figure 2: A: GPR modeled data...

... is a feature that can be used to interpolate signals that are spatially aliased in higher frequencies. We refer to the resultant method as AA-OIP (Anti-alias Optimal Interpolation with Priors). Related interpolators Recently, Moore and Ferber (2008) have extended the interpolator based on Yen’s 4th...

Paper Number: SEG-2009-3158
... SUMMARY We propose a new De-alias seismic data reconstruction algorithm, which combines minimum-weighted norm interpolation (MWNI) with band extension via modulation (BEM) method effectively. In the algorithm, we use two stages to finish MWNI reconstruction. First, we reconstruct the low...

... and re- interpret the section. In the process of model- building, tests were run with various apertures, mutes, stretch filters and anti- alias filters in order to determine the optimum migration parameters. By nature, Kirchoff summation algorithms have aliasing problems which are amplified in the near...

... of the group is not the ideal shape for an anti-alias filter! The effect of a boxcar filter is a sinc function. The sinc function does not suppress all the high spatial frequencies, nor does it pass the lower spatial frequencies untouched. As a consequence part of the aliased groundroll energy may remain...
