Abstract

Real time passive millimeter-wave imaging systems have a wide variety of uses from aircraft navigation and landing in fog to detection of concealed weapons. A useful imaging system for flight platforms requires a large number of pixels and a high frame rate combined with a small antenna volume and a lost cost. We present a millimeter-wave imaging system which uses 32 MMIC low noise amplifiers to display a 60 X 75 pixel image at a 30 Hz frame rate. The system's pupil-plane phased array architecture allows for a relatively thin large aperture antenna. A remotely located processor utilizes microwave guiding circuit boards to perform phase and frequency discrimination on the radiation received by the antenna array.
