The work shows the method of interference immunity estimation of airborne secondary security radar responders as open one-channel queuing systems with failures. It considers the presence of unintentional (intrasystem) and deliberate (correlated and uncorrected) interference in the request channel when servicing the request signals of imitating-stable mode and imitating-unstable mode. It is shown that the absence of spatial and temporal differences between the request signals and deliberate correlated interference leads to a significant decrease in interference immunity of aircraft responders and, as a result, to a decrease in the quality indicators of the querying identification systems in general.
