Conclusions

I presented an amplitude-preserving function for the AMO operator that enables accurate implementation of an AMO algorithm on regularly sampled data. The derivation of the amplitude is consistent with the definition of most interpreters for preserving peak amplitudes of reflection events. Numerical experiments showed that an AMO operator based on Zhang's DMO cascaded with its true inverse best reconstructs data amplitudes. The new amplitude function defines an amplitude-preserving azimuth moveout.
