METHOD OF IDENTIFYING OBJECTS Russian patent published in 2014 - IPC G08B3/00 G01S13/82 

FIELD: physics; control.

SUBSTANCE: invention relates to remote sensing systems used to identify objects, including moving objects, particularly railway or motor transport containers. The system for identifying objects comprises a microwave and signal processing unit 1, a transceiving antenna 2, a reader 3, a switching on device 4, a data transmission line 5, a sensor 6, a piezoelectric crystal 7, a microstrip transceiving antenna 8, electrodes 9, buses 10 and 11, a set 12 of reflectors, a carrier frequency generator 13, a circulator 14, a mixer 15, an amplifier 16, a demodulator 17, a signal processing unit 18, a storage device 19, a matching device 20, a control device 21. The central information processing device 30 comprises a receiving antenna 23, a high frequency amplifier 24, a search unit 25, a heterodyne 26, a mixer 27, an intermediate frequency amplifier 28, a phase-shift keyed signal detector 29, spectrum analysers 31 and 33, a phase doubler 32, a comparator unit 34, a threshold unit 35, a delay line 36, a switch 37, narrow band-pass filters 38 and 40, a phase halver 39, a phase detector 41 and a recording unit 42.

EFFECT: high accuracy and reliability of identifying objects without self-contained power sources using radio-frequency labels operating on surface acoustic waves and compound phase-shift keyed signals.
