The work analyzes the process of functioning of aerial surveillance search radar systems: friend or foe identification systems, secondary surveillance systems, radar systems near navigation. This demonstrates that which construction existing radar interrogation systems can be represented as an asynchronous network for transmitting radar information, also an order processing signals interrogations can be described in a form a one-channel queueing system with failures. Using of simple coding of request and/or response signals does makes impossible ensuring a given quality level of service of airspace surveillance and traffic control systems in the face of significant intra-system errors, and also intentional interference correlated or/and uncorrelated. This article provides the mathematical description of a request servicing process and examines the dependence of the probability of an error in the system on the length of a data packet. An influence not only single and group errors in the radar information transmission channel was taken into account, but also the requirements for the permissible number of repeated requests. An algorithm for adaptive control of the transmission of radar information was proposed. This algorithm involves analyzing the characteristics of the wireless data transmission medium and makes it possible to dynamically change various parameters of the access control level to the physical medium depending on changes in the signal propagation environment. Consequently, it becomes possible to find optimal settings for a specific distribution environment, ensuring optimization a length а data packet of packets data being transmitted.
