P076 MODIFIED KIRCHHOFF PRESTACK DEPTH MIGRATION USING THE GAUSSIAN BEAM OPERATOR AS GREEN FUNCTION Abstract 1 Upon the introduction of a Gaussian Beam superposition integral into the true amplitude Kirchhoff migration integral the migration operator becomes an integral whose kernel is a convolution over the projected Fresnel zone. Introduction In the past two decades Kirchhoff migration has evolved from a kinematic imaging-only technique to an inversion operator capable of handling attributes for AVO/AVA analysis. Bleistein (1987) based on Beylkin (1985) was one of the first to propose an inversion operator that used the Kirchhoff algorithm for seismic attributes determination. Schleicher
