Calculation of Secundary Surveillance Radar Operational Parameters

Sekundarni nadzorni radar obrađuje podatke na temelju odaslanog koda transpondera. Ovisno o radarskom sustavu na zemlji te uvjetima kroz koji se signal propagira, snaga odaslanog signala varira. Kako bi zrakoplov bio detektiran potrebno je da signal na interogatoru ima snagu iznad minimalne detektibilne snage. Proračunom karakterističnih slučajeva prikazani su primjeri propagacije signala u različitim uvjetima atmosfere. Proračun i grafički prikaz izrađeni su u programskom jeziku Matlab.The Secondary surveillance radar processes the data based on the transmitted transponder code. The power of the transmitted signal varies depending on the radar system on the ground and the conditions through which the signal propagates. It is necessary that the signal on the interrogator has a power above the minimum detectable power in order for the aircraft to be detected. The calculation of the characteristic cases showsexamples of signal propagation under different atmospheric conditions. The analysis of the problem is made in the programming language Matlab
