摘要:
Wave extrapolation methods are of considerable technological interest. When the wave field is axisymmetric or contains lower order azimuthal components, extrapolation may be performed in the radial direction from data recorded on a single sideline. This yields important reductions in the data acquisition and computation processes. This paper provides a theoretical basis for spectral‐domain radial extrapolation and describes numerical simulations and an experimental application.
