Abstract

The paper is devoted to recovery of local rapid perturbations (scatterers/reflectors) of a priori known macrovelocity background by means of linearized asymptotic inversion of multi-shot multi-offset seismic data. Inversion procedure is done via application of some speci£c integral transform to input data with respect to source/receiver positions and time frequency. Result of this transform is represented as an asymptotic series with leading term being superposition of some specific spatial Fourier constituents of desired local perturbations. Composition of these constituents is totally determined by range of time frequencies and geometry of acquisition system. The approach is tested on Sigsbee2A synthetic data set. Numerical results are presented and discussed.
