The system of airspace control provides to a large extent the State security and air traffic safety, which determines in itself the level of requirements to protection of information processes of its functioning. Modern systems for monitoring airspace solve, as is known, the following main objectives: - conducting continuous reconnaissance of the air space; - assessment of the air situation and identification of violations of the air space use order; - delivering the results of radar data to the government, administrative, military management and air traffic control management. Reconnaissance of the air space is realized with the surveillance systems whose main task is to give answers: where is a flying object (FO) and who is it. The systems of primary [1-3] and secondary [2-3] surveillance radar give jointly an answer to these questions. The primary radar systems answer the question “where" and the secondary surveillance radar (SSR) systems i.e. the systems of “friend or foe" identification (IFF), answer the question “who". The quality of these two surveillance systems information, defined by the interference immunity of the discussed surveillance systems, is determined, to a large extent, by the quality of the information support of the airspace control system. The immunity of the primary radar systems is considered adequately in the existing sources of information, but there is a gap in consideration of the IFF interference immunity. So, the problem of reply signals (RS) processing was raised in [4-6]. However, the SSR are twochannel systems: they contain the interrogation channel and the response channel. This fact should be taken into account when assessing the probability of information support with these surveillance systems[7,8]. The aim of the work is to assess the quality of information support of the airspace control system using the systems of “Friend-or- Foe" identification. The main [...]
