FIELD: radio engineering, communication.
SUBSTANCE: radiofrequency identification system for military installations includes a reader 3, a sensor 6, and a central information processing device 30. The difference of claimed invention is that central information processing device 30 comprises an asynchronous detector 27, a low-pass filter 28, a registration unit 29, a unipolar valve 31, a storage device 32, a threshold unit 33 and a delay line 34.
EFFECT: increasing interference immunity and reliability of radiofrequency identification of military installations by eliminating additional receiving channels and the phenomenon of reverse work.
