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 ...

Space-based detection of space debris by photometric and polarimetric characteristics

AOPC 2017: Space Optics and Earth Imaging and Space Navigation, 2017
The number of space debris has been increasing dramatically in the last few years, and is expected to increase as much in the future. As the orbital debris population grows, the risk of collision between debris and other orbital objects also grows. Therefore, space debris detection is a particularly important task for space environment security, and ...

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.

Monte Carlo simulation of detecting space debris with lidar

SPIE Proceedings, 2010
ABSTRACT On the basis of analysis and processing of space background radiatio n, the article gives the detection probability when the lidar detecting space debris, and compare the random va riable which is produced by Monte Carlo method with the detection probability, then get the detection results. The results reveal that, the detection model can well

The detection capability of space-based combined system for space debris

SPIE Proceedings, 2016
It is urgent to tracking and making a catalog for space debris, since they are such serious threats to spacecraft. Space-based detection possess a great of development potential for its low energy consumption, high precision and miniaturization and other features.

Microwave radar imaging and detection algorithm for space debris

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
There are more than one hundred thousand space debris with the diameter beyond one centimeter, the exist of space debris has been seriously threatening the safety of the on-the-track space probes. Small space debris, diameter between one and ten centimeter, is focused as the main target in this paper, on the base of the single range matching filtering ...

Streak detection algorithm for space debris detection on optical images.

Any image processing object detection algorithm somehow tries to integrate the object light (Recognition Step) and applies statistical criteria to distinguish objects of interest from other objects or from pure background (Decision Step). There are various possibilities how these two basic steps can be realized, as can be seen in the different proposed

Research on active and passive detection for space debris

AOPC 2017: Optical Sensing and Imaging Technology and Applications, 2017
With 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 ...
