合成孔径雷达(合成孔径雷达)卫星作为对地观测卫星的一种，由于其在对地图像采集过程中不受周围环境影响的优点，得到了大量的发展。为了获得较高的成像质量，要求合成孔径雷达天线具有较大的直径。然而，卫星运载火箭的内部空间有限，这使得合成孔径雷达天线需要设计成可展开的，以便在运载火箭中折叠和在太空中展开。在本研究中，考虑到卫星的目标任务，选择了可展开卫星天线的各种设计因素的取值。应用所选择的设计因子值设计了可展开卫星天线的构型，并通过仿真观察了可展开卫星天线在卫星机动过程中的变化。
Large number of SAR(Synthetic Aperture Radar) satellites, one type of earth observation satellite, have been developed as they have the advantage of not being affected by surrounding environment during the earth image acquisition. In order to gain high image quality, SAR antenna should have large diameter. However, internal space of satellite launch vehicle is limited and this leads SAR antenna to be designed deployable so that it can be folded in launch vehicle and unfolded in space. In this research, values of various design factors of deployable satellite antenna were chosen considering satellite`s target mission. Configuration of deployable satellite antenna was designed by applying the chosen values of design factors, and variation in deployable satellite antenna during satellite maneuver was observed through simulation.
