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.
