Air-space-ground integrated networking method oriented to air moving target tracking

The invention discloses an air-space-ground integrated networking method for air moving target tracking, and belongs to the technical field of air-space-ground integrated networks. The method comprises the following steps: collecting scene information, reading and classifying near-earth satellite information, selecting an optimal orbit, selecting an optimal on-orbit satellite, calculating a shortest path, predicting a position at a next moment, and judging whether a scheme is ended or not according to a path distance threshold value. According to the method, the problem of rapid change of the space-air-ground integrated network topology is solved, the exact network topology at different moments and the motion constraint condition of the satellite orbit can be obtained, and the optimal link switching decision condition can be obtained. According to the method, a large amount of mathematical calculation is reduced, the optimal network link and the link switching time can be obtained through simple calculation,
