Abstract
A 8mm passive focal plane image system which could be applied for airplane ils was introduced in this paper. System parameters were designed for this special purpose. Since high gain must be obtained based on limited feed antenna's aperture, dielectric-loaded horn antenna was designed as the feed of parabolic reflector antenna to receive the power radiated from the object. 8mm direct detector receivers were connected directly to the feed horn antennas to avoid undesirable blockage. From the imaging results, the concrete buiding could be distinguished easily from the sky in the passive millimeter wave image.
