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 ...

Mission Planning Tool for Space Debris Detection and Tracking with the MeerKAT Radar

International Radar Conference, 2019
Sustained human activity in Space has had the unfortunate consequence of creating space debris which accumulate in orbit. The rubble cloud which arose in the LEO regime poses a significant collision risk for spacecraft.

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

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.

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
