- 1.
- Compute the maximum and minimum NMO correction required in the data according to the offsets, reflection times and velocities.
- 2.
- Use the previous information to precompute all the NMO time shifts in the frequency domain by application of an all-pass non-stationary linear phase filter.
- 3.
- Take the inverse Fourier transform to get the precomputed impulse responses in time domain.
- 4.
- For each trace, form the impulse response matrix selecting from the precomputed ones those required according to the NMO shifts appropriate to that trace.
- 5.
- Carry out the filtering by multiplying the trace by the the impulse response matrix.
