    Vitek, S.; Hozman, J. (Společnost pro radioelektronické inženýrství, 2003-12)
    For many applications in image processing it is necessary to know model of imaging system, which has been used for image data obtain. Knowledge about system can be used for the simulation of an image data in astronomy ...
  • Statistics of Radio Refractivity Derived from Prague Radiosounding Data 

    Rezacova, D.; Fiser, O.; Ramon Saez, L. (Společnost pro radioelektronické inženýrství, 2003-12)
    Vertical gradient of radio refractivity in the lowest 100 m is derived from the meteorological radio-sounding data of the Prague-Libus station. The data cover the measurements at the terms 00, 06, 12, and 18UTC, and the ...
  • Clear-Air Propagation Modeling using Parabolic Equation Method 

    Grabner, M.; Kvicera, V. (Společnost pro radioelektronické inženýrství, 2003-12)
    Propagation of radio waves under clear-air conditions is affected by the distribution of atmospheric refractivity between the transmitter and the receiver. The measurement of refractivity was carried out on the TV Tower ...
  • Utilization of MATLAB in Simulation of Linear Hybrid Circuits 

    Brancik, L. (Společnost pro radioelektronické inženýrství, 2003-12)
    In the paper a MATLAB-based method for simulating transient phenomena in linear hybrid circuits containing parts with both lumped and distributed parameters is presented. Distributed parts of the circuit are multiconductor ...
