- •
To address the complications of measuring the time to frequency spectrum for 3D TL random noise, we use a modified STFT.
- •
By matching the real data amplitude with the phase of modeled noise, a 3D time-lapse modeling noise is produced.
- •
The resulting noise realization matches the coherent characteristics of the measured noise, as desired.
- •
The method is fast and easy to implement for the generation of many realizations of noise for statistical approaches.
- •
The use of the presented method for a statistical determination of plume detectability is a part of the future work.
