Huygens' principle in reverse. Targeting between complementary wavefronts provides a solution to a reversed Previous HitrefractionNext Hit profile that is independent of the refractor velocity. The agreement between two one-way solutions imposed thereon proves correctness. Reversed Previous HitrefractionNext Hit profiling is the only geophysical method affording an Previous HitinterpretationNext Hit which can be proved correct on the Previous HitdataTop alone. However, application of this fact is limited by recording conditions and velocity complexities.
