Optimization of the Probability of Transmission of Flight Data in the Response Channel of Secondary Radar Systems

In the work presented it is shown that the use of time-domain codes and positional codes as request signals and response signals, as well as the implementation aircraft transponder based on the principles of an open single-channel queuing system with failures lead to a significant decrease in both the noise immunity of the information systems under consideration when deliberate correlated interference operates in the request channel, and to a decrease in information security. The approach is based on the analysis of both information request signals and response signals, as well as the principles of constructing secondary radar systems in general and an aircraft transponder in particular. It is also shown that with the optimal choice of the transmission probability of flight data from air objects and the number of channels for processing received flight data, depending on the possible number of air objects located at the same azimuth, it is possible to optimize the probability of transmission of flight data in the response channel of secondary radar systems.
