Abstract:SUMMARYThis paper seeks to reconstruct the parameters of elastic layered media such as P-wave velocity, S-wave velocity, density and thickness from the multioffset seismic reflection data. Since the data are highly non-linear to the low-wavenumber components, the non-linear waveform inversion method, with the aid of generalized ray theory, is proposed to solve this problem in space-time domain. As opposed to the layer-stripping method, the present method attempts to invert all layer parameters simultaneously, … Show more
