Abstract:
A new multidimensional time/multi-frequency higher order spectral(HOS) transform
is proposed for transient signals with nonlinear polynomial variation of
instantaneous frequency: the short time higher order chirp spectra (HOCS) based
on the higher order chirp-Fourier transform and time-domain windowing technique.
The proposed transform is compared with the classical multi-frequency HOS based
on the Fourier transform. It is shown that the proposed transform is more
effective for processing of transient processes in comparison with the classical
transform.
