Abstract:
A millimeter-wave imaging system for generating an image of a scene, said system comprising:two or more beacons in the scene transmitting a millimeter-wave radiation signal, each of said beacons including a modulator that modulates the millimeter-wave signal in a distinct manner with an identifier indicative of the beacon; and a millimeter-wave camera independently located from the beacons responsive to the radiation signal from the beacons, said camera including a plurality of receivers, each receiver including an antenna, a detector and a demodulator, said antenna receiving the signal, said detector converting the signal to an electrical representation, and said demodulator demodulating the signal to determine the identifier of each of the beacons in the image to distinguish and decipher the beacons.
