Calculation of Frequency-Territorial Separation Norms for Decimeter Radio-Electronic Means

Anotace: The paper considers the main models of radio wave propagation used in the calculation of radio lines in the line-of-sight area. It has been shown that to calculate the frequency-territorial separation norms, the Vvedensky reflective model is advisable. The methodology for calculating the frequency-territorial separation norms and the peculiarities of its application for radio-electronic means operating in the decimeter-wave range are determined. Failure to take into account the attenuation multiplier during radio wave propagation within the scope of the Vvedensky formula leads to an error in the calculation of the interference power at the input of the interference receiver-receptor and to an erroneous increase in frequency separation during the development of frequency-territorial separation norms for decimeter radio-electronic means.
