Analysis of resolution limits of VTI anisotropy with full waveform inversion

Abstract

Summary Here we analyze the resolution limits of multiparameter inversion and describe correlations between the parameters depending on their spatial resolution. The analysis is based on the singular value decomposition of the far-field linearized inversion operator in the wavenumber domain. We show principle limitations of P-P and P-SV scattering data inversion such as decrease of sensitivity of finite-frequency data at low and high wavenumbers. The theoretical predictions are in a good agreement with the numerical results obtained in spatial domain.
