In this abstract, we discuss some fundamental issues of full waveform inversion (FWI). We believe that a successful waveform inversion should emphasize traveltime information and downplay the role of amplitude information. This is achieved by using an objective function that measures the cross-correlation between observed and synthetic data. Further, we propose that for FWI of reflection data in the data domain, migration and demigration processes are necessary to reduce the wellknown cycle-skip problem.
