摘要
对小卫星对地观测高分辨率成像系统进行了综述。介绍了国内外有极高分辨率（0．5～1．0m）、高分辨率（1．8～2．5m）和中高分辨率（4-10m）小卫星光学成像系统的性能，并与合成孔径雷达（SAR）成像系统进行了比较。给出了小卫星光学成像系统、SAR高分辨率成像系统和卫星平台的关键技术。讨论了未来小卫星及其高分辨率成像系统技术的发展趋势。
The high resolution imaging system of small satellite for earth observation was reviewed in this paper. The performances of the optical imaging system of the small satellite with very high resolution 0.5-1.0 m, highresolution 1.8-2.5 m and medial-high resolution 4-10 m were introduced and compared with synthetic aperture radar （SAR） system. The key technologies of the optical imaging system, SAR high-resolution imaging system and platform in the small satellite were given out, The technology development trends of the small satellite and its high resolution imaging system were discussed.
