Notes:
A method is presented to image a reflecting discontinuity of the earth parameters. As model data we take the boundary integral representation in which we employ a locally plane reflector approximation. We separate the horizontal phase from the vertical phase in the data by employing a Radon transform with respect to the horizontal source and receiver coordinates. Carrying out a high-frequency analysis and taking the vertical slowness as an independent variable, the resulting Fourier integral is inverted to the space-time domain. We arrive at a function with a laterally variant vertical traveltime that represents a space-time image of the profile of the interface as the envelope of the first arrivals. The method shows clearly how the data in the source-receiver domain have to be collected.
