摘　　要：天基空间监视是地基空间监视的延伸,需要高性能CCD作为成像器。首先回顾CCD的发展,并分析天基空间监视对CCD的技术需求。电子倍增CCD是超低读出噪声和高量子效率的新型器件。说明电子倍增CCD的原理,并介绍CCD97在天基空间监视中的应用分析。讨论电子倍增CCD在空间监视中的应用技术,如倍增增益的控制及器件格式拼接等。Space-based space surveillance is the extension of ground-based system, and needs the high performance CCD as its imager. Development of scientific CCD is firstly reviewed, and the demands of space surveillance for CCD are analyzed. Electron multiplying CCD is the novel imager that has uhra-low readout noise and high quantum efficiency： The principle of EMCCD is later presented and CCD97 is introduced to spacebased space surveillance, Several problems of EMCCD in space surveillance are discussed, such as the control of the multiplying gain, mosaic arrays technology, etc.
