Abstract EN
The Hartley transform, as in the case of the Fourier transform, is not suitably applicable to nonstationary representations of signals whose statistical properties change as a function of time.
Hence, different versions of 2-D short time Hartley transforms (STHT) are given in comparison with the short time Fourier transform (STFT).
Although the two different versions of STHT defined here with their inverses are equally applicable, one of them is mathematically incorrect/incompatible due to the incorrect definition of the 2-D Hartley transform in literature.
These definitions of STHTs can easily be extended to multi-dimensions.
Computations of the STFT and the two versions of STHTs are illustrated based on 32 channels (traces) of synthetic seismic data consisting of 256 samples in each trace.
Salient features of STHTs are incorporated.
