Up: Brown: Imaging operator for
I introduced a new time-imaging operator for pegleg multiples, called HEMNO. HEMNO
operates on single CMP gathers, making it computationally efficient and predictable
in terms of amplitude behavior. I demonstrate that HEMNO can correctly account for
moderate variation in reflector geometry with position, and that in a joint imaging
context (LSJIMP), HEMNO accurately models both the vertical positioning of peglegs
and some of the focusing effects with offset.
