Wavelet transforms allow efficient analysis of signals in one or more dimensions. The signals may be expressed at different scales of resolution. This provides schemes for compression of informations in image and speech processing. The mathematical f

Shot gathers from the Parkfield, California, deep crustal seismic reflection line, recorded in 1977 by COCORP, reveal coherent events having horizontal to reverse moveouts. These events were migrated using a multioffset three‐dimensional Kirchhoff

The application of the Born approximation to the scattered wave field, followed by a WKBJ and far‐field approximation on the propagation Green’s function for a slowly varying background medium, leads to a simple integral relation between the dens
