Synchrosqueezing-based Transform and its Application in Seismic Data Analysis
Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals. Spectral decomposition can reveal the non-stationary characteristics which cannot be easily observed in the time or frequency representation alone. Various types of spectral decomposition methods have been introduced by some resear...

متن کاملSignal Reconstruction From The Modulus of its Fourier Transform
The problem of signal reconstruction from the magnitude of its Fourier transform arises in many applications where the wave phase is apparently lost or impractical to measure. One example of such an application that has attracted a substantial number of researchers in recent years is Coherent Diffraction Imaging (CDI). CDI is a “lens-less” technique for 2D and 3D nano-objects reconstruction wit...
متن کاملA reversible transform for seismic data processing
We use the nonstationary equivalent of the Fourier shift theorem to derive a general one-dimensional integral transform for the application and removal of certain seismic data processing steps. This transform comes from the observation that many seismic data processing steps can be viewed as nonstationary shifts. The continuous form of the transform is exactly reversible, and the discrete form ...
