• W2314008249 abstract "The frequency sampling of frequency-domain reverse-time migration is defined by the Nyquist-Shannon theorem. An integration (summation) of the images over all frequencies during imaging condition corresponds to zero-lag cross-correlation in the time domain. We propose a method to interpolate images between sparse-frequency samples in order to achieve frequency-domain two-way migration with reduced cost in wave modeling. Using a high-frequency asymptotic expression of the image, we show numerically that this assumption applies to a wide range of frequencies that contribute to the significant part of the final image. The image interpolation is then carried out by fitting the asymptotic coefficients at sparsefrequency samples in the least-squares sense. We employ a regularized nonstationary autoregression to determine the traveltime and amplitude terms. The choice of sparse-frequency samples can be made according to the frequency spectrum of the source wavelet and/or data. Several synthetic examples demonstrate the validity of the proposed approach." @default.
