Embodiment 1

[0050] This embodiment provides an automatic tracking method applied to space-based space targets, which is used in a space-based space target automatic tracking system including satellite platforms, image acquisition equipment, turntable control equipment, two-dimensional tracking turntables, and target tracking processing equipment . Before executing the automatic tracking method, the ground control information needs to select the space target to be tracked, and calculate the target initial parameters of the space target, inject monitoring target parameters into the star through the measurement and control channel, and the target initial parameters include target Start detection time, noise suppression threshold, reference upper and lower limit of motion direction, reference upper and lower limit of angular velocity, minimum value of dispersion effect, stability of satellite platform, initial wave gate value; Injected data on . see figure 1 , which is shown as the flow of ...

Embodiment 2

[0083] This embodiment provides an automatic tracking system 1 applied to space-based space targets, please refer to Figure 4 , showing the principle structure of an automatic tracking system applied to space-based space targets, the automatic tracking system applied to space-based space targets includes an image acquisition device 11, a target tracking processing device 12, a turntable control device 13, and a two-dimensional tracking turntable 14 , and a satellite platform (not shown).

[0084] The image acquisition device 11 in the automatic tracking system 1 applied to space-based space targets is used to acquire images containing space targets to be tracked. In this embodiment, the image acquisition device 11 is a guiding camera.

[0085]The target tracking processing device 12 includes a first judging module 121, a second judging module 122, a third judging module 123, a target detection module 124, a fourth judging module 125, an initial module 126 for the number of t...

Abstract

The invention provides an automatic tracking method and system applied to a space-based space target. The method includes the steps that an image including the space target needed to be tracked is collected; whether an automatic tracking task is executed for the first time or not is judged; if yes, the space target is detected and tracked, and a current second miss distance of the space target is calculated; if not, whether a tracking step executed in the process of automatic tracking is executed previously or not is judged; if yes, whether the number of continuous-losing times of space object tracking exceeds a preset threshold value of the number of losing times of space object tracking or not is judged, and if yes, the space object is detected again; if not, tracking is executed, and a current second miss distance of the space object is calculated; if the tracking step is not executed, the space object is detected again. The influences on the tracking process by a satellite dynamic base are eliminated, the requirement for automatically capturing and tracking the space object is met, when the target is located in a view field, the tracking state can be captured at once without forecasting the priori knowledge of the target through the ground, the method is reliable, miss distance calculation is precise, and the space-based tracking requirement is met.

Description

technical field [0001] The technical field of satellite communication of the present invention relates to a tracking method and system, in particular to an automatic tracking method and system applied to space-based space targets. Background technique [0002] In recent years, with the rapid development of military aerospace in various countries around the world, the United States believes that its space dominance is under potential threat. To this end, the U.S. military is vigorously promoting the space control strategy, stepping up the development of space countermeasure weapons and equipment, and actively improving defensive and offensive space countermeasure capabilities on the basis of enhancing space situational awareness, and promoting the actual combat of space countermeasures. At the same time, with the changes in the international environment, the development of U.S. space confrontation has also shown new characteristics: a "space countermeasure" strategy combining...
