A new technology of passive millimeter-wave aperture synthetic camera is an imaging technology that can receive the radiation from observed objects and does not require a millimeter-wave source and have potential applications. It offers very significant advantages of simpler system, lower cost, real-time imaging, higher resolution and near-all-weather capability etc. as well as has arisen attentions of scientific and military surveillance. In this paper, aimed at circumstances of earth observations of airborne, the principles of passive millimeter-wave aperture synthetic imaging are introduced, the results of simulated computation show that: (a) In cases of 10000 meter height, 100 MHz width of frequencies and ±300 field of view, the emitted power from terrain is 9.0 watt for 8 mm waveband and 68.0 watt foe 3mm waveband respectively. Such a radiation power is sufficient for airborne remote sensing. (b) The coverage of visibility function and angle resolution foe Y-type of antenna arrays is better than T-type of antenna arrays. The results of this paper are helpful for design of systems for passive millimeter-wave aperture synthetic imaging of airborne.
