For the geometry presented in Figure and
using equation () show that the reflection point
displacement measured along the reflector is
where *t*_{cmp} is the traveltime from the CMP location
(point **F**) to the reflector and back (or the segment **FG**
in time units). The length of the segment **FG** is
given in equation (). This equation appears
in Levin's (1971) classic paper, and is also the first
equation Dave Hale uses when explaining DMO in his SEG
course notes.
