Moveout-based wave-equation migration velocity analysis |

for each z,x | (7) |

we have

To find the relation between and , we differentiate equation (8) with respect to and , which yields

in which we can find

indicate the first and second derivatives in (depth). Let

Then substituting the above two equations into eq. (9) leads to

which is eq. (2).
