The use of streak observations to detect space debris

International Journal of Remote Sensing, 2017
Man-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

Analysis on the detection capability of the space-based camera for the space debris

SPIE Proceedings, 2016
Based 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

System for an Active Detection of Orbital Debris in Space

Journal of Spacecraft and Rockets, 2016
The 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.

Evaluation of Oversampling Strategies in Machine Learning for Space Debris Detection

2019 IEEE International Conference on Imaging Systems and Techniques (IST), 2019
In recent years, the number of resident space objects has increased dramatically. The chances of space objects colliding with each other are increasing, thus posing a threat to active satellites and future space missions. Identifying and detecting space debris is essential in ensuring the security of space assets.

Innovative techniques for small space debris detection

1998
The large number of man-made uncontrolled objects orbiting the Earth is becoming a serious threat to space activities. Existing models of this orbital debris population are inadequate, particularly in the debris size range between sub-millimeter and tens of centimeters.

Detection ability of space-based optical observation system to space debris

SPIE Proceedings, 2015
For supplying the reference to the spaced-based optical observation system design and performance analysis, the space-based observation mode for space debris is established. Considering the geometry size, the material characteristics, and the distribution region of the debris, the visual magnitude of space debris is calculated in the condition of ...

Algorithms and applications for detecting faint space debris in GEO

Acta Astronautica, 2015
Abstract The GEO region is a kind of unique and precious resource, it is of great importance to prevent space debris collisions in this region. Surveying space debris in GEO and extracting the relevant information automatically are rather challenging tasks due to several factors.
