Embodiment Construction

[0026] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0027] To achieve the above object, the present invention is achieved through the following technical solutions, as figure 1 and figure 2 As shown, the design of a step-by-step all-sky scanning search device is based on the range of the field of view of the camera 12 and the imaging conditions of the camera 12, and the rotation range of the one-dimensional rotating mechanism 11. A multi-camera 12 combined scanning system based on a one-dimensional rotating mechanism 11 is designed to meet the requirements of full-sky area coverage scanning.

[0028] Specifically, the step-by-step all-sky scanning search device is composed of two search mechanisms 10, which are respectively placed on the upper an...

Abstract

The invention discloses a stepping type all-day area scanning searching device and method, and the device consists of two searching mechanisms which are respectively placed at the upper side and the lower side of a satellite and are responsible for 180-degree airspace searching tasks; Each searching mechanism is composed of a one-dimensional rotating mechanism used for stepping rotation and two cameras arranged on the one-dimensional rotating mechanism. A view field of each camera is 30 degrees * 30 degrees, and a splicing view field formed by the two cameras is 60 degrees * 30 degrees. And each searching mechanism realizes 60-degree * 180-degree full-view-field coverage by virtue of the rotation of the one-dimensional rotating mechanism. According to the method, the strategy problem of multi-target detection and tracking in an all-day area is solved, the rapidity of multi-target detection is improved, and the false alarm rate is reduced; the rapidity of multi-target tracking is improved; therefore, detection and continuous tracking of the spatial unnatural celestial body target are realized. And a feasible engineering foundation is provided for on-orbit satellite anti-collision avoidance.

Description

technical field [0001] The invention relates to the field of space technology, in particular to a step-by-step all-sky area scanning search device and method. Background technique [0002] With the rapid development of space technology, unknown targets including out-of-control satellites, space debris and space junk are increasing year by year. A variety of unknown targets will interfere with the normal operation of satellites, and even threaten the safety of satellite operations. The collision between the American Iridium 33 satellite and the Russian obsolete satellite is the first satellite collision accident in history. This incident has caused the space anti-collision technology to attract the attention of all space powers. The discovery, identification and threat assessment of unknown space targets has become the primary solution for anti-collision technology. The problem. On the other hand, during the mission of cleaning up space junk, satellites have orbit changes a...
