Faint Space Debris Detection Algorithm Based on Small Aperture Telescope Detection System

Research in Astronomy and Astrophysics, 2022
Ground-based optical observation has unique advantages in space target observation. However, due to the weak light-gathering ability of small-aperture optoelectronic observation telescopes, the space debris in the image is weak and easily drowned in ...

Simulation System for Space Debris Intelligent Detecting

2021
Space debris has become a major potential safety hazard to the on-orbit spacecraft, which must be considered when launching a spacecraft. A simulation verification system which ground-based and can simulate the debris detecting onboard was established. The system consists of three sub-systems.

Space Debris Detection and Analysis

1994
Abstract : A 40 cm telescope with an intensified CCD detector and video recording was used to detect space-debris objects. Participation in the ODERACS experiment showed that objects as small as 5 cm could be detected with this size telescope. Image analysis techniques were tested to enhance the low S/N debris streaks in the recorded video signals, and

Space-borne radar detection of orbital debris

Proceedings of GLOBECOM '93. IEEE Global Telecommunications Conference, 2002
Orbital debris in low-Earth-orbit (LEG) poses an increasing threat to the Space Station Freedom (SSF). A combined ground-based/on-orbit radar detection system can provide adequate warning to minimize the collision threat. The paper discusses the unique features on an on-board radar, its contributions to solving the problem, simulation results from ...
