Have a look at the resolution of prestack depth migration for any model, survey and wavefields.

摘要: Summary Integral equation approaches to acoustic imaging within the Born or Kirchhoff approximation give compact algorithms for depth migration, using pre-calculated Green’s functions. They moreover direct access a fundamental parameter: scattering wavenumber. This parameter controls resolution of migrated section. Using efficient methods obtain asymptotic functions, functions can now be calculated numerically in both 2D and 3D. Any location any background model considered. All kind surveys subselections shot/ receiver couples are possible. As multi-field is available, new set wavenumbers may Resolution important at survey planning stage define optimal acquisition. also essential interpretation sections, i.e., discriminate between true reflections artificial events due bandlimited signals limited-aperture. Such effects should corrected prior measurements reflectivity.
