Resolution of prestack seismic migration

Ludek Klimes


Explicit approximate equations describing the physical meaning of the migrated sections are derived. The imaged combination of elastic parameters (reflectivity) depends on the selection of the polarizations of the incident and back-propagated wavefields and on the directions of propagation. The migrated section is then approximately the convolution of the unknown exact reflectivity with the resolution function depending on the aperture and on the form of the imaging time function.
