空间目标天基光学观测模式分析

对空间目标的监视可采用地基和天基两种方式实现。与地基观测相比，天基观测在空域覆盖性和监视时效性等方面具有较大优势，空间目标天基观测技术已成为当今空间领域的前沿性技术。目前，许多国家和组织都在大力发展空间目标天基观测技术。天基光学观测可采用光学栅栏、特定天区和地球同步带搜索方式实现空间目标的捕获；可通过恒星跟踪和天文定位方法获取空间目标的位置信息；可采用等待或跟踪方式实现对目标的成像。

Analysis on the space-based optic observation mode for space object

Space surveillance usually adopts ground-based and space-based means. Compared to ground-based observation, space-based observation has advantages in coverage of space and in time. Space-based observation technology for space object becomes most important technology in the field of space. Now many countries and organizations have energetically developed space-based observation technology. The space-based optic observation applies optic fence, specifying space area and geosychronous orbit means for searching, star-tracking means for orienting, waiting or tracking means for imaging.
