  • Ultra-Short Pulse Excitation in a Semi-Infinite Waveguide by a Relativistic Electron Bunch 
    Balakirev, V.A.; Onishchenko, I.N.; Sidorenko, D.Yu.; Sotnikov, G.V. (Радиофизика и радиоастрономия, 2002)
    The theoretical investigations and simulation are performed for the emission of a relativistic electron bunch during the injection into a semi-infinite vacuum/dielectric waveguide. The exact solution of the problem is ...
  • Ultra-Wideband Communication System with High Data Rate 
    Immoreev, I.J.; Sudakov, A.A. (Радиофизика и радиоастрономия, 2002)
    The ultra-wideband communication system with high data rate is considered. Information in the system is transmitted by train of short pulses, which have duration about 1.0 ns. The hardware realization of the system is ...
  • Ultra Wideband Dipole Antenna 
    Bakhrakh, L.D.; Los', V.F.; Shamanov, A.N. (Радиофизика и радиоастрономия, 2002)
    This paper considers the antenna-feeder device which helps to realize a new method of antenna excitation. This method enables to transfer dipole antennas into the ultra-wideband category. The paper also demonstrates the ...
  • Ultra-Wideband (UWB) Radar for the Remote Measuring of Main Parameters of Patient's Vital Activity 
    Immoreev, I.J.; Samkov, S.V. (Радиофизика и радиоастрономия, 2002)
    The capability of UWB radar usage in medicine the for remote measuring of patient’s heart activity and respiration is considered. The measuring method is described and practical results of the tests are cited. The possibility ...
  • Using Alternative Aperture Geometry Horn Antennas in Wide-Band Multifrequency Measurements 
    Drobakhin, O.O.; Kondratyev, Y.V. (Радиофизика и радиоастрономия, 2002)
    Application of horn antennas in non-destructive testing by multifrequency reflectivity measurements has several advantages in comparison with simple antennas such as open-ended waveguide, in particular, higher gain and ...
  • 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 ...
