| 摘 要： | 以小卫星平台的空间动态目标探测为应用背景,采用短积分时间的凝视成像方式、LVDS并行传输的高帧频数传模式、折反式光学系统以及部分国外工业级器件的集约化设计思路,设计了星载微型凝视式可见光CCD遥感器。文章首先介绍了光学系统和电子电路的设计和性能;然后阐述了其可靠性保证技术路线,并通过整机的鉴定级环境试验验证该技术路线的可行性,最后对该遥感器性能进行测试,结果表明在总质量小于2kg,曝光时间小于2ms条件下,其静态MTF大于0.2,动态MTF大于0.16,信噪比大于49。 |

| Abstract: | Miniaturized spaceborne staring CCD remote sensor is designed in order to detect dynamic target in outer space.Staring imaging with short integration time and LVDS parallel transmission with high frame frequency are used.Moreover,an optical system with refraction and reflection and some foreign components of industrial lead are adopted.In this text,not only the optical system and electrical circuit but also the designing method of reliability is introduced,whose feasibility has been verified by reliability experiment.The results are that its mass is less than 2kg and integration time less than 2ms,static MTF greater than 0.2,dynamic MTF is greater than 0.16 and SNR more than 49. |
