Reverse‐time extrapolation of the recorded wavefield (a boundary‐value problem), and computation of the excitation‐time imaging condition for each point in a 3D volume (an initial‐value problem), are both performed using a second‐order finite‐difference solution of the full 3D scalar wave equation. The algorithm is illustrated by processing synthetic data for a point diffractor, an oblique wedge, and the French double dome and fault model.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380861290901673472","@type":"Researcher","foaf:name":[{"@value":"WEN‐FONG CHANG"}]},{"@id":"https://cir.nii.ac.jp/crid/1380574092886465792","@type":"Researcher","foaf:name":[{"@value":"GEORGE A.
