Air-based space fragment optical detection and tracking system and method

Abstract

The invention discloses an air-based space fragment optical detection and tracking system and method. The system comprises a large-view-field telescope, a small-view-field telescope, a laser range finding machine, and a holder. The method comprises the steps: capturing a rough azimuth angle and a pitch angle of a target through the large-view-field telescope; capturing a precise azimuth angle and a pitch angle of the target through the small-view-field telescope; and measuring the distance with the target through the laser range finding machine. The system employs a passive imaging and laser range finding combination system which consists of the large-view-field telescope, the small-view-field telescope and the laser range finding machine, achieves finding, capturing and tracking of small objects in space through the technology of optical imaging, overcomes the limit that a laser radar is difficult to detect small objects, is low in system power consumption, can quickly and precisely detect the distance and azimuth of the target, and is long in detection distance.

Description

technical field [0001] The invention belongs to the technical field of image-based non-contact automatic measurement, and in particular relates to a space-based optical detection and tracking system and method for small space debris. Background technique [0002] With the rapid increase in the number of man-made celestial bodies launched by humans, there are more and more space targets. A large number of man-made celestial bodies that have expired have become uncontrollable space targets flying in space. Some man-made celestial bodies break up into a large number of small fragments after collision. For example, the abandoned Russian satellite Cosmos 2251 collided with an American satellite, resulting in a large amount of debris. On the other hand, there are space natural targets such as meteorites in space. Space vehicles in service, abandoned artificial celestial bodies, debris, and space meteorites constitute all space flight targets. Space targets generated by humans ...
