OBJECT IDENTIFICATION SYSTEM AND METHOD

An identification system and method of use thereof is provided, the system (1) comprising at least one transceiver cell (3) comprising an antenna component (7) which receives a part of an incoming signal (11) from an object (13), and a processor which processes the part of the incoming signal to extract identification information of the object, wherein the processor comprises a frequency downconverter/mixer unit comprising a coupler which produces first and second phase quadrature signals, a first mixer which receives the first signal and mixes it with the part of the incoming signal to produce a first output signal comprising object identification information, and a second mixer which receives the second signal and mixes it with the part of the incoming signal to produce a second output signal comprising object identification information, a phase shifter which receives the second output signal and adds a 90 degree phase shift to the signal to produce a phase shifted second output signal comprising the object identification information, a sideband signal filter which receives the first output signal from the frequency downconverter/mixer unit and receives the phase shifted second output signal from the phase shifter, and operates to produce a sideband signal of the part of the incoming signal which comprises the object identification information, and an object identification component which receives the sideband signal from the sideband signal filter, extracts the object identification information therefrom, and uses the object identification information to identify the object. La présente invention concerne un système d'identification et son procédé d'utilisation, le système (1) comprenant au moins une cellule d'émission-réception (3) comprenant un composant d'antenne (7) qui reçoit une partie d'un signal entrant (11) à partir d'un objet (13), et un processeur qui traite la partie du signal entrant pour extraire des informations d'identification de l'objet. Le processeur comprend une unité d'abaissement/mélange de fréquence comprenant un coupleur qui produit des premier et second signaux en quadrature de phase, un premier mélangeur qui reçoit le premier signal et le mélange avec la partie du signal entrant afin de produire un premier signal de sortie comprenant des informations d'identification d'objet, et un second mélangeur qui reçoit le second signal et le mélange avec la partie du signal entrant afin de produire un second signal de sortie comprenant d
