Comparative Analysis of Noise Immunity Systems Identification Friend or Foe

In the presented work, based on the presentation of the total flow of requesting signals, intra-system correlated and uncorrelated interference, as well as intentional correlated interference, such as Poisson's, an estimation technique was developed and a comparative analysis of the noise immunity of both aircraft responders and existing Systems Identification Friend or Foe as a whole. A comparative assessment of the energy secrecy of the aircraft responders of the existing Systems Identification Friend or Foe is also given. This allowed a comparative analysis of the noise immunity of existing Systems Identification Friend or Foe. It is shown that the existing Systems Identification Friend or Foe in terms of the structure of the aircraft responder, allows the interested party to use it unauthorized both to obtain information and to suppress intentional correlated interference.
