Fomel (2004) define an image space transformation from subsurface offset to reflection and azimuth angle as:

Substituting the prestack migration image (subsurface offset domain) in equation 1 into equation 4 we obtain the expression for the prestack migration image in the angle-domain that follows:

The synthetic data can be modeled (as the adjoint of equation 5) by the chain of linear operator and the angle-to-offset transformation operator acting on the model space,
