The application of lidar in detecting space debris
SPIE Proceedings, 2008The accumulation of space debris is expected to present an increasing threat to orbital aerostat. To develop and use space resource continually and in security the detecting technology for space debris has to be improved. The paper firstly introduces the concept of space debris and their common detection means, and then introduces the application of

Space Debris Detection and Analysis
1994Abstract : 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

Simulation System for Space Debris Intelligent Detecting
2021Space 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-borne radar detection of orbital debris
Proceedings of GLOBECOM '93. IEEE Global Telecommunications Conference, 2002Orbital 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 ...

Research on active and passive detection for space debris
AOPC 2017: Optical Sensing and Imaging Technology and Applications, 2017With the increasing frequency of human space activities, the number of spacecraft and space debris on track is increasing. In order to process the information of debris after detecting it in a very short time and reduce the size, weight and power consumption of the detection system at the same time, an active and passive composite optical detection ...

Analysis on the detection capability of the space-based camera for the space debris
SPIE Proceedings, 2016Based on the maximum detection range, the detection capability of space-based camera for space debris is analyzed in the paper. We perform grid generation method on the debris target and analyze the shadowing effects among the grids, building the geometry modeling of cone target sequentially. The calculation model of optical infrared characteristics is

Analysis of Defocus in Space Based Space Optical Debris Detection
ACTA PHOTONICA SINICA, 2016the reasons of the generation of defocus were discussed and the defocus change was analysed from the relative distance, atmospheric pressure and temperature change. the modulation transfer function model was proposed to study the image quality influenced by defocus. then different defocus value leading image blurry was simulated. the simulation results

The use of streak observations to detect space debris
International Journal of Remote Sensing, 2017Man-made space debris orbit around the Earth at many altitudes in different orbits and many launches add further debris to already congested orbits. The European Space Agency (ESA) GSTP-funded Optical IN-SITU Monitor project started in 2016 and aims to analyse the end-to-end processing pipeline from image acquisition to the extracted positions of space

System for an Active Detection of Orbital Debris in Space
Journal of Spacecraft and Rockets, 2016The physical properties and the number density of micrometeoroids and orbital debris are important parameters of the space environment. High-velocity interaction with spacecraft can be of serious concern for the operation of long-lived space structures and for man operations in space.
