A novel optimal STFrFT and its application in seismic signal processing

摘要

This paper used the rotation property of FrFT to put forward a new concept called generalized time fractional bandwidth product (GTFrBP) criterion, which is derived from generalized time bandwidth product(GTBP) , then it gave a way to design the optimal window function based on GTFrBP and implement the optimal short time fractional Fourier transform(STFrFT) under the criterion. Then we carried out a simulation on theory model. Finally, the paper applied it in seismic signal processing. The result showed that this method can obtain high resolution spectral decomposition of seismic signal.
