摘要
从品质因子、极化方式、定量化程度、信息获取维度等方面,对现有星载SAR技术发展阶段进行划分,给出了不同发展阶段星载SAR的特征和典型工作模式,并对新一代星载SAR技术发展趋势进行了分析。最后,简要介绍高分三号(GF-3)卫星的基本特性,并分析高分三号卫星所处的发展阶段和历史地位。
This paper divides the stages of spaceborne SAR technology development from the as-pects of merit factor,polarization mode,quantification degree and information acquisition dimen-sion.The characteristics and typical working modes of spaceborne SAR at different stages of de-velop is given.The development trend of new generation spaceborne SAR technology is analyzed. Finally,the basic characteristics of GF-3 satellite are briefly introduced,and the development stage and historical status of GF-3 satellite are analyzed.
