摘　　要：介绍了实现稀疏孔径系统的迈克尔逊干涉和斐索干涉的两种干涉成像原理,讨论了实现稀疏孔径探测和成像的子孔径的空间布局、相位一致和图像恢复,分析了载荷展开,卫星编队中的编队卫星轨道设计、空间基线测量与控制,以及光机技术等工程化实现的关键技术。The principles of the two types of interferometry named Michelson and Fizeau sparse aperture technology（SAT） were introduced in this paper.The major field of SAT including the array configuration,the phase synchronization and the image restoration was described.The key technologies towards its space application,which were the payload deployment,orbit design and measurement and control of baseline in space in satellite formation flying,and optic instrument,were analyzed.
