Abstract

The goal of seismic imaging is to produce the reflection operator at target depth. This reflection operator is independent of the acquisition parameters and is an intrinsic property of the medium parameters (Berkhout, 1982). In the so-called Angle-versus-Angle (AVA) analysis one is concerned with the behaviour of the reflection operator as a function of the strike angle of the incident wavefield at a particular interface. In order to enhance the AVA analysis we propose a biangular decomposition of the seismic data. In the resulting domain the axes are related to the strike angle of the incident wavefield with respect to the normal at the interface and the local dip angle of that interface. Operating in this way we go from from acquisition dependent parameters to intrinsic medium parameters.
