摘要
从地平坐标系和时角坐标系出发,运用坐标旋转公式推导出光学合成孔径成像技术中干涉阵排列和uv覆盖之间的几何关系式,以特定观测天区为例,在南京模拟三孔径Y型阵,并运用蒙特卡洛法对2个目标函数分别优化,将其优化结果进行比较,找到比较适合该文的目标函数。
Based on the horizon coordinate system and angle coordinate system, the formula between interferometric array and uv coverage of optical synthetic aperture imaging was derived using coordinate rotation. An Y-type in Nanjing was taken as an example to make the observation in a specific sky area, and the Monte Carlo method was used to optimize two objective functions, and the optimization results were compared to find more suitable objective function.
