| 摘 要： | 运用模拟退火算法对由20-30根天线组成的二维圆周综合孔径阵列进行优化排列,得到优化排布结果。在此基础上依据综合孔径成像的基本原理,分析了毫米波的成像算法,在u-v域运用了栅格化处理（Gridding方法）和线性插值方法。运用该成像算法对已优化排布的阵列进行了仿真,并进一步讨论了天线数目、插值方法等因素对成像特性的影响。

| Abstract: | A method called simulated annealing array composed of 20-30 antennas. Based on the is adopted for the optimization of a two-dimensional circle optimized array and principle of synthetic aperture imaging, some problems about millimeter wave imaging algorithm using Gridding treatment and linear interpolation in UV domain are studied. And then the imaging of the optimized array is simulated and analyzed. The influences on imaging quality by number of antenna and the linear interpolation are also discussed. |

| Keywords: | synthetic aperture optimization of array u-v coverage visibility function mm-wave imaging |
