小卫星合成孔径雷达技术探究

Study on SAR Technology for Small Satellites

小卫星开发周期短、可靠性高、投资风险小、具有快速响应能力,已成为当前的研究热点。根据小卫星合成孔径雷达(SAR)的发展趋势,提出一种轻小型平面板式SAR设计方案,并在设计中采用了适应小卫星平台的技术手段。最后,给出了小卫星SAR设计的实例仿真。

Small satellite becomes a research focus now,for its characteristic of short period, high reliability,low cost and rapidly response.In this paper,a kind of spaceborne mini-SAR payload with panel antenna is designed,which is suitable for small satellite platform. Then an example of SAR design for small satellites is given.
