Lazorenko O. The Propagation of Ultra-Wideband Radio Signals in Near-to-Earth Space

The investigation object is the ultra wide-band (UWB) radio signal propagation percularities in near-to-earth and cosmic spase. The investigation targets are the UWB signal dispersive distorsion estimation in the Earth's ionosphere and magnetosphere, interplanet plasma and the UWB radar optimal parameter valuation for the near-to-earth and cosmic space (ECS) remote sounding. The investigation methodes and technics. There are analitical and numerical calculations. The theoretic results and news. The UWB signal dispersive distorsions in ESC space are estimated, the radar equation for UWB signals is modified, the UWB radio signal use for the ECS radar is suggested and such radar optimal parameters are calculated. The practic results and news. The possibilities of the new communication chanal creation and of that real modification, of the new methode creation for ECS spaceremote radar are proved. The instilision object and grade are the new communication chanal and the new ECS space remote radar method c reations, the instilision is planed. The use tracts are the radar, communication, remote sounding.
