Abstract
We have developed an algorithm to model reflections with AVO via the Radon Transform. The algorithm is a modification of the classical sparse Radon transform and splits the seismic gather in two Radon gathers: one that models the strength of the reflections at zero offset, the other adds capability to model the AVO signature. The new Radon operator is inverted using the IRLS algorithm. Our synthetic and real data examples show an improvement with respect to the classical sparse Radon transform at the time of estimating primaries with reduced amplitude distortion.
