    Abstract
  • Based on the advantages of phased array and synthetic aperture imaging method in passive millimeter-wave imaging, a collaborative passive millimeter-wave imaging system was developed for real-time and high resolution imaging in human security application. In the horizontal orientation, by applying annealing algorithm, different aperture horn antennas were determined for the improvement of the phased array performance, which was generally compared with the maximum main beam effective and most smoothable sidelobe level. In vertical orientation, the synthetic aperture, namely, the sparse antenna array was designed by the criterion of the most uniform redundant baseline, while baseline absence should be avoided. Finally, simulation results reveal that with the optimized antenna array the requirement of increasing singal-to-noise ratio (SNR) in power measurement in the collaborative passive imaging system can be fulfilled.
