METHOD FOR RADAR IDENTIFICATION WITH PROVISION OF DETERMINATION OF AUTHENTICITY OF INTERROGATION SIGNAL Russian patent published in 2004 - IPC

FIELD: radio detection and ranging.

SUBSTANCE: the invention provides for a high reliability of identification of the own object and makes it possible to essentially limit the enemy chances for use of the proved and retransmitted series of interrogation signals by provision of identification system aids with stable electronic timers, transmission of coded information in the interrogation signal on the state of the interrogator time scale at the moment of signal normalization and realization of check-up of correctness of the transmitted information by the responder according to the coincidence of it within the preset limits with the indications of the own times and realization for this check-up of a two-threshold circuit taking into account the precision characteristics of the used timers, signals delay time for propagation and the degree of variation in time of the disagreement of indications of the timers of the interacting objects. The offered principle of use on the responder of interrogators as identificators interacting with it at the given moment, the values of divergence of the indication of the own timer and indications of the timers of the interrogators enables the responder to check the process of interaction with the interrogators by limiting the production of responds to each of them in the preset quantity, a reliable identification of the object and interruption of responder servicing.

EFFECT: provided check-up of the process of interaction with the interrogators.
