Paper Abstract

Passive mm-wave synthetic aperture imaging system applies the interferometric principle to sample brightness temperature in the spatial domain and retrieve the image by inverse Fourier transformation. An optimization model for synthesis aperture array was set up from the theory of u-v coverage. Using that model, a ten-antenna array in a pie slice area was optimized at different pie slice radius angle by simulated annealing algorithm. These antennas were to rotate around the radius center by 10 times with each time π/10 to form full u-v coverage. In this paper, the non-instantaneous imaging theory of rotating u-v coverage synthesis aperture system is analyzed. A method called Gridding was adopted to deal the data in u-v plane so as to use IFFT. In the end the imaging algorithm is used to get PSF of synthesis aperture system with the optimized arrays by computer simulating. The PSF at different pie slice radius angle was compared and analyzed.
