Energy Distribution on CSP gathers as they approach a scatterpoint

Luis Alfonso Galdona, John C. Bancroft

CSP gathers that have the same migration aperture contain identical input energy as they contain the same input traces. It is the arrangement of these input traces with offset that allows constructive and destructive interference to form coherent hyperbolic energy when the CSP gather is located at a scatterpoint. When the CSP gather moves away from a scatterpoint the input energy will tend to cancel. This effect is illustrated with a number of examples.
