Progress in foreign groundbased optoelectronic

The present situation of advanced groundbased space target detecting systems at abroad are introduced in this paper. Then, two kinds of ground based optoelectronic tracking systems for detecting the space target, 35 m telescope and 367 m Advanced Electric Optical System(AEOS) telescope, are described and the working performance and working missions for two telescopes are given. On the basis of the design concept and advanced technological schemes reported above, the technologies relating to “ground based optoelectronic system for satellite imaging” are discussed. For the overall scheme of “large aperture ground based optoelectronic observation equipment for the satellite imaging”, the viewpoint to build a 18 m altazimuth telescope with adaptive optics technology is put forward, which suggests that the telescope is designed to be an optical table with expandable function.
