The study considers a two-channel data transmission system as an SSR model and assesses its relative data capacity subject to intentional (correlated and uncorrelated) and intra-system interference as well as fluctuation (masking effect) noise in the request and response channels. It is shown that the aircraft transponder design built on the principles of a single-channel queuing system with denial of service has a significant impact on Secondary Surveillance Radar relative data capacity and the information security of both the aircraft transponder and the entire Secondary Surveillance Radar.ensecondary surveillance radarair traffic controlair objectaircraft transpondercooperative surveillance systemsintra-system interferenceidentification friend or foeinformation supportArticle
