Abstract

For the current ground-based space target surveillance system in China, the task response time is long, the target monitoring system is time-sensitive, and the space-based on-orbit monitoring current monitoring system usually has a small field of view, and the field of view is generally 6°, the monitoring range is limited, and the tracking arc is limited. This paper proposes a design of space-based large field of view monitoring camera. The selection and experimental analysis of high quantum efficiency and low noise detectors, detector refrigeration design and thermal test verification, big angle and high suppression ratio stray light design, this key points of high sensitivity detection camera for dim target are discussed in this paper, and lay the foundation for quickly acquiring the position and orbit information capability of long-range dim targets, providing high-precision cataloging of fast-moving dark space targets, improving the monitoring performance and real-time performance of surveillance systems in China.
