摘　　要：稀疏孔径系统应用于航天遥感领域可以获得与全孔径系统相当的空间分辨率,而整个系统的体积和重量明显减小。分析典型Golay6结构,给出稀疏孔径光学系统调制传递函数的表达式,分析Golay6稀疏孔径系统的调制传递函数,并进行模拟成像。Golay6结构是非冗余的稀疏孔径结构。The same spatial resolution can be achieved as the full aperture systems, when the sparse aperture systems are applied in the space remote field, and their volumes and weights are lower than those of the full aperture systems. The configuration of Golay6 is analyzed and the formulas of the modulation transfer function for the sparse aperture system has been given out. Image simulation is also processed. It is shown that Golay6 is a kind of redundant sparse aperture configuration.
