  • Dispersive distortions of the fractal ultra-wideband signals in plasma media 
    Chernogor, L.F.; Lazorenko, O.V.; Onishchenko, A.A. (Вопросы атомной науки и техники, 2018)
    The results of numerical modeling of dispersive distortions of the model high-frequency fractal ultra-wideband (UWB) signals propagating in linear and parabolic plasma layers are considered. The character of the ...
  • Earth – Atmosphere – Geospace as an Open Nonlinear Dynamical System 
    Chernogor, L.F.; Rozumenko, V.T. (2008)
    The concept of the Earth-atmosphere-ionosphere-magnetosphere (EAIM) system as a complex open dissipative nonlinear dynamical system whose most important property is trigger mechanisms for energy releases has been validated, ...
  • Fractal analysis of the fractal ultra-wideband signals 
    Chernogor, L.F.; Lazorenko, O.V.; Onishchenko, A.A. (Вопросы атомной науки и техники, 2015)
    The results of fractal analysis of the fractal ultra-wideband (FUWB) signals were proposed. With usage of the continuous wavelet transform the time-frequency structure of that signals was investigated. Calculating the box ...
  • Multi-fractal analysis of the earth’s electromagnetic field time variations caused by the powerful geospace storm occurred on September 7-8, 2017 
    Chernogor, L.F.; Garmash, K.P.; Lazorenko, O.V.; Onishchenko, A.A. (Вопросы атомной науки и техники, 2018)
    The results of multi-fractal analysis of time variations of the Earth’s electromagnetic field caused by the powerful geospace storm occurred on September 7-8, 2017 were considered. To obtain the most detailed results, the ...
  • Reflection of the Ultra-Wideband Signals from Plasma Layers 
    Chernogor, L.F.; Lazorenko, O.V. (Радиофизика и радиоастрономия, 2002)
    This paper is concerned with the temporal distortion caused by the dispersion of ultra-wideband signals reflecting from linear and parabolic plasma layers. The magnitudes of the expected effects have been estimated for the ...
  • System spectral analysis of the fractal ultra-wideband signals 
    Chernogor, L.F.; Kravchenko, S.G.; Lazorenko, O.V. (Вопросы атомной науки и техники, 2015)
    The theoretical basis and practical peculiarities of the system spectral analysis are briefly considered. The necessity and the expediency of simultaneously application of different linear and non-linear integral transforms ...
  • The physical effects associated with Chelyabinsk meteorite's passage 
    Chernogor, L.F.; Rozumenko, V.T. (Вопросы атомной науки и техники, 2013)
    The main effects associated with the February 15, 2013 Chelyabinsk bolide (Chebarkul meteorite) have been estimated. The major amount of energy release (approximately 0.2 Megaton) occurred near 25 km altitude where the ...
  • Wavelet Analysis and Ultra Wideband Signals 
    Chernogor, L.F.; Lazorenko, O.V.; Lazorenko, S.V. (Радиофизика и радиоастрономия, 2002)
    The wavelet analysis is offered to be used for the description of the ultra wideband signals. The expediency of such approach is justified. It is displayed, that wavelets are ultra wideband signals. The wideband indexes ...
  • Аspects of electromagnetic compatibility at remote sensing of ionosphere in radiophysical observatory of Кharkiv National University 
    Magda, I.I.; Chernogor, L.F. (Вопросы атомной науки и техники, 2018)
    Specific responses of radio receivers of various type and frequency range under conditions to receiving of both a sole intense ultrashort signals and combination of information and interference ultrashort signals are ...
