The paper analyses the cause of anomalous stretch of normal moveout in seismic data processing and the characteristics digital normal moveout correction.

Then the trace gather undergoes velocity analysis, normal moveout correction and stack to bring seismic migrated section ( This is called scattering point imaging).

Therefore, our work extends the application of the nonhyperbolic moveout equation to the ATI media and makes the nonhyperbolic moveout correction and stack of the far-offset in the ATI media.
