Description

[0001] The present invention relates to a method of operating an integrated type peer identifier,

The present invention relates to a peer identifier, and more particularly, to a method of driving an integrated peer identifier in which an answering machine and a signal processor are integrally manufactured.

The PIA Identifier is mounted on a tram or ground platform and is intended to minimize the damage of false positives by performing peer identification by transmitting and receiving the Ka-band RF signal of the question / answer to the unidentified platform. In other words, for the unacknowledged platform, that is, to respond to the target, first, the peer of the target should be identified. To this end, the peer identifier transmits the signal containing the question to the target. For a question signal of a peer identifier, a response is usually sent to the interrogation signal, since the target may be considered non-aliens if it does not respond. The peer identifier that has sent the challenge signal receives the response signal sent from the target and analyzes it to identify the peer of the target. To identify such a peer, the peer identifier may include an interrogator that transmits the interrogation signal, a responder that responds to the interrogation signal, and a processor that receives, processes, and analyzes the response signal from the responder. An example of such a pie identifier is shown in Korean Patent Registration No. 10-1292069 and Korean Patent Registration No. 10-1030745.

On the other hand, although the PIA discriminator developed for the next tram was applied in improving the performance of the command armored vehicle, additional equipment was required to be applied to the command armored vehicle without the battle management system, and the unnecessary question function was included, Which is the cause of the rise. In other words, since the next trampier identification system is operated by a separate computer or an electric field management computer, it can be operated only by a pier identification system, making it impossible to operate in a command armored vehicle without a tramp management computer. In addition, when a non-aggressive armored vehicle is equipped with a module for inquiry function that is not needed for a non-aggressive weapon system and a responder and a processor are separate units, There is a problem that the size, weight, and price are increased.

Therefore, it is necessary to remove the unnecessary function among the functions of the aggressive system so that it can be applied to non-aggressive weapon systems such as armored vehicles, and miniaturize the cryptographic module developed for the next train, Development is needed.
