Space debris detection with fast grid-based learning

2020 IEEE 3rd International Conference of Safe Production and Informatization (IICSPI), 2020
Fast space debris detection is valuable to space safety and space vehicle operation. In this paper, we proposed a fast space debris detection method with grid-based learning. The image divided into 14×14 grids, and then the fast grid-based neural network

The capability analysis of the bistatic radar system based on Tianlai radio array for space debris detection

Advances in Space Research, 2019
The bistatic radar system has been one of the effective methods to detect the space debris in low earth orbit (LEO). Tianlai radio array with cylindrical-parabolic antennas is designed for dark energy detection, which has large field of view and high ...

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.

Feasibility Study on a PCL Radar for Space Debris Detection

2019 IEEE Aerospace Conference, 2019
There are more than 19,000 objects in earth orbit as of 2018. These space objects are tracked by the space surveillance network (SSN). We found it necessary of own radar facilities for searching a lost satellite and space debris through an accident on a small satellite of the past. To establish an own radar facility by a civilian agency as a laboratory

A space debris detection and tracking method for wide-field surveillance

Symposium on Novel Photoelectronic Detection Technology and Application, 2023
Space debris detection is important for space asset protection and space situational awareness. The current environment of man-made satellites and space debris objects in Earth orbits increases rapidly, so does the probability of collision between them ...

Space debris: modeling and detectability

SPIE Proceedings, 2017
High precision orbit determination is required for the detection and removal of space debris. Knowledge of the distribution of debris objects in orbit is necessary for orbit determination by active or passive sensors. The results can be used to investigate the orbits on which objects of a certain size at a certain frequency can be found.

A Survey on Image Processing based Techniques for Space Debris Detection

2022 IEEE Bombay Section Signature Conference (IBSSC), 2022
Space debris is the nonfunctional objects revolving in the outer earth orbit. The high-speed debris projecting to Kessler's syndrome is a threat to active satellites.

The application of lidar in detecting space debris

SPIE Proceedings, 2008
The 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
