Mi llimeter-wave imaging is typically implemented by means of mechanical or e lectrical scanning which requires long data acquisition times or a large n umber of active components. Passive millimeter-wave imaging systems that c apture thermal signals and operate similarly to optical cameras are very c ostly because they need to employ highly sensitive receivers due to therma l radiation being extremely low power at millimeter-wave frequencies. This talk presents a newly developed millimeter-wave imaging technique called active incoherent millimeter-wave (AIM) imaging which combines the benefit s of active and passive millimeter-wave imaging. This approach combines th e high signal-to-noise ratio capabilities of active millimeter-wave imagin g systems with the fast image formation potential of passive millimeter-wa ve imaging systems. The combination is achieved by illuminating the scene with multiple spatially distributed noise transmitters that mimic the rand omness of thermal radiation. Starting from our earlier work in microwave f requencies\, I discuss the system design and calibration approach\, along with an experimental demonstration of a millimeter-wave active incoherent digital array. The array can generate millimeter-wave video at very high f rame rates\, and millimeter-wave imaging results include video captured at 652 frames per second of a sphere in pendulum motion. The use of stray re flections from a small set of communication transmitters is also examined\ , and incoherent imaging results using WiFi and 5G signals are presented.\ n\nSpeaker(s): Dr. Stavros Vakalis\n\n800 W Campbell Rd\, Richardson\, Tex as\, United States\, 75080 LOCATION:800 W Campbell Rd\, Richardson\, Texas\, United States\, 75080 ORGANIZER:emil.draganov@ieee.org SEQUENCE:15 SUMMARY:Active incoherent millimeter-wave systems for high-speed imaging wi th extremely sparse antenna arrays URL;VALUE=URI:https://events.vtools.ieee.org/m/577820 X-ALT-DESC:Description: <br /><p>Electromagnetic signals in the frequency r ange of 30&ndash\;300 GHz can penetrate through materials like clothing\, fog\, and smoke\, and at the same time provide image reconstruction with f ine spatial resolution.
