Abstract

Whether you can use a sparse set of source angles in delayed-shot migration, or not, depends on how well your actual set of sources approximates (or can be made to approximate) an unaliased “antenna”. If you have a well sampled source antenna, then sparse angles can be used to create high-quality images since you can transform your data into the equivalent delayed-line-source experiment. If your collection of sources does not satisfy this requirement, then you may have to use a large number of angles to construct artifact-free images.
