An Investigation into the Vulnerability of a Typical Identification Friend or Foe (IFF) Interrogator Receiver.

摘要

The performance of a typical IFF interrogator receiver was evaluated against various types of received signals. The received signals that were considered represent environments of intentional as well as unintentional interference. The performance of the receiver was determined by studying the effects of an envelope detected version of the received signal on the decoder circuit in the interrogator. Probabilities of error and false alarm were approximated using a computer simulation for decoder operation.
