Three‐Dimensional Migration Algorithms
Raffaele Persico · 2014
This chapter provides three-dimensional (3D) migration formulas, namely for the data gathered at the air-soil interface in common offset on a nonmagnetic soil and without magnetic targets. The source is assimilated to a Hertzian dipole, and the received signal is approximated as the projection of the field along the direction of the receiving dipole in the observation point. The chapter exposes the physical reason why in the formulas of the 2D migration in the time domain, the datum is integrated versus the time, whereas in the homologous 3D formulas the integration along the time disappears.
