Asymptotic Construction of a Procedure for Plane-Wave Synthesis and Migration,

Abstract

This report outlines the construction of a more exact operator for the migration of plane-wave seismograms. The objective here is to construct a procedure which will produce an output appropriate for both structural imaging and velocity inversion; that is, an output which is a direct indicator of reflection strength. The calculations presented here allow the reflector to have an arbitrary complex two-dimensional shape. While the reflector is assumed to be two-dimensional, the propagating wavefields are assumed to be three dimensional and are responses from point sources. The analysis presented here deals with the case of a constant background velocity field. More general cases are now being examined.
