Abstract
Summary
We extend the apex shifted hyperbolic Radon transform by scanning for both the apex and asymptote shifts of travel time hyperbolas in order to match both reflections and diffractions more closely. The new transform dictionary is built using Stolt migration/demigration operators to increase its computational efficiency. This new transform is used to interpolate a common shot gather from the 2D BP/SEG salt model using inversion with sparsity constraint. Our tests show that the new transform is an efficient tool for interpolating seismic data in the presence of diffractions.
