Abstract

We retrieve transmission compensated subsurface primary reflections from the reflection response measured at the surface. This is achieved by filtering the reflection response. The application of this scheme does not require model information. In this process, the reflection response is convolved and correlated with itself. The result after each convolution and correlation is truncated in the time domain. Free-surface and internal multiple reflections are removed and the two-way transmission effects in the primary reflections are compensated for in one step. The output of this scheme is a data set that contains only transmission compensated primary reflections. The obtained data set can be used as input to retrieve an artefact-free image of the medium. We illustrate the method with a two-dimensional example that shows how free-surface and internal multiple reflections are removed and transmission loss in primary reflections are compensated for. The method can have a wide range of applications in 3D strongly scattering media that are accessible from one side only.
