Quasi-noise illumination in mm-wave imaging: From concept to realization

The paper describes the W-band single-pixel imaging de tector with a pulse-noise source in the Tx-channel and the direct detecting circuitry in the Rx-channel. The detector is maintained on X-Y programmable scanner controlled by LabView interface which is integrated with MatLab used for online image reconstruction. The application of an incoherent illumination generated by the frequency-limited quasi noise source improves image quality compared with the coherent mode widely used in conventional active imagers.
