Slope Sensitive Dip Move-Out Correction
, by Shuki Ronen
Spatial aliasing reductioin by dip move-out (DMO) is rederived and discussed
in both time and frequency domains. A synthetic example in which an aliased
zero offset section is compared with a stack after DMO is given. The DMO
reduces most of the aliasing noise; the remaining noise results form under-
sampling in the offset and in midpoint directions. Theroetically the aliasing
in the offset direction should not be a problem, this is shown in a synthetic
example. A way to reduce the remaining midpoint aliasing noise by using a
spatial derivative is described.
