Lightweight Visible Light Camera Technology for Weak Space Target Detection
OPTOELECTRONIC IMAGING AND MULTIMEDIA TECHNOLOGY IX(2022)
摘要
Asteroid detection is of great significance for studying the origin and evolution of the solar system, collision warning, space resource development, etc. through the networking of micro-satellite constellation, large-scale and high-frequency observations of asteroids can be achieved. Aiming at the above requirements, through the collaborative optimization of imaging chains, this paper develops a 5kg high-performance visible camera for weak space target detection, which has the detection ability better than 13 Mv, which is equivalent to detecting a target with a diameter of 10cm at a distance of 1000km, and can be carried on a 10kg micro-satellite. Through the networking of micro-satellites, give play to the advantages of cluster detection, realize the high-sensitivity and high-frequency detection of asteroids, and provide high real-time data support for asteroid research and early warning.
