FIELD: identification of objects, mainly of large dimensions, for detecting infringing products, containers for foodstuffs, and also controlling and tracking movement of load and transportation flows. ^ SUBSTANCE: in accordance to objects identification method, passive radio mark is fastened on an object, radio mark is radio probed by transmitter, signal is encoded, electric signal formed by radio mark is emitted and then received by receiver, while radio probing of object is realized in by frequency-phase and amplitude-modulated signal, signal is compressed in time, its impulse power is increased, and encoding of signal is performed by combining various topologies of opposite-rod transformers and forms of signal emitted by transmitter, while only one topology matches each form of signal. ^ EFFECT: increased distance of reading and increased reliability of detection of information about object. ^ 2 dwg |
