Scientific Work
Scientific interests of O. V. Lazorenko are following: the ultra-wideband (UWB), non-linear and fractal signals and processes, time-frequency and fractal analyses of the signals and processes, the non-linear and fractal physics and radio physics.
Scientific achievements are following:
1. For ultra-short and fractal UWB signals, the modeling of dispersive distortions appearing during their propagation in dispersive media, in particular, in the near-to-Earth and cosmic spaces and in inter-planet medium has been performed.
2. The basic equation of remote radio sounding (the basic equation of radar) for case of UWB signal application has been generalized. The possibility of appearing of the “electromagnetic missile” effect has been taken into account.
3. Taking into account the possibility of the signal dispersive distortion appearing, the parameters of radars for remote radio sounding of the near-to-Earth and cosmic spaces with UWB signal usage have been calculated.
4. The idea of application of new non-traditional methods of analysis (the wavelet analysis, the Wigner’s, Choi-Williams’ and Born-Jordan’s transforms) for time-frequency processing of UWB signals and processes has been developed. The new classes of wavelets (the Kravchenko-Rvachov analytic wavelets) and non-linear integral transforms (the Wigner-Kravchenko and Choi-Williams-Rvachov transforms) based on the atomic function theory have been created.
5. The new classes of UWB signals and processes (fractal, non-linear, random and pseudo-random ones, ones with changing mean frequency) have been approached. Their properties and possibilities have been investigated.
6. With energetic participation of O. V. Lazorenko, the new methods of analysis of the signals and processes, in particular, the adaptive Fourier transform and the system spectral analysis have been created.
7. On the order of the National Academy of Sciences of Ukraine, a thorough (in three parts) analytical review of a new scientific direction – fractal radiophysics – was created.
8. New complex methods of fractal analysis of the signals and processes, namely, the generalized fractal analysis, the dynamic fractal analysis and the method of the corrective function have been created.
9. The concept of second-order fractals is proposed, as well as a modern classification of monofractal analysis methods.
10. By conducting thorough time-frequency and fractal analyzes of experimental data, the fractal nature of processes in the geospace caused by the action of a powerful non-stationary source of energy release (gravitational waves, powerful geospace storms, powerful earthquakes, the fall of large cosmic bodies, etc.) has been proven.
