Research of the noise immunity of the airport surveillance radar primary channel on model at influence of active noise-like interference

Article deals with evaluation of noise immunity primary channel Airport Surveillance Radar (ASR) when exposed to organized interference. On the basis of the classical equations of a radar-location mathematical and program models of the ASR primary channel and the director of active hindrances are developed. As of modeling objects were taken real ASR-1AC and jammer (hypothetical station of active hindrances), using as suppression methods, radar, and the formation of a barrage of noise and remission simulation copies of radio signals of ASR. Researches ASR noise immunity to the effects of active noise-like and simulation of interference, both the main and side-lobe of the antenna pattern. To assess the primary channel ASR noise immunity to noise impacts, calculated the probability of correct detection of aircraft approaching the airfield and border of a zone of suppression. The analysis of results of researches of a noise stability of ASR to influence of active hindrances is made.
