Arrival time inversion and traveltime function
© 1989 Society of Exploration Geophysicists. All rights reserved. The traveltime inversion techniques usually involve modeling the earth above the reflector. The paper discusses an alternative approach, vhich deals with the modeling of a traveltime function (TTF) and does not require the earth modeling. The migration equations are formulated in such a way that they relate the problem to the TTF. Since the TTF is needed only in the limited range of its variables, it may be modeled by a simple function with a few adjustable parameters. The deeper the reflector, the smaller the number of parameters required. Therefore, the method may be attractive for deep reflector data. Some restrictions applied to the modeled TTF are discussed.
