摘　　要：为实现高轨光学成像卫星对动目标的连续跟踪,基于最大限度地利用观测视场范围、节省姿态机动所需能源消耗的原则,设计了一种应用观测视场九宫格的动目标跟踪策略,通过对相邻观测视场重叠覆盖宽度设计避免动目标丢失。建立一套仿真系统,对提出策略的有效性进行仿真验证。仿真结果表明:相较于动目标临近越出观测视场范围就调整相机视轴指向动目标的策略,文章提出的跟踪策略能够通过更少的姿态机动次数实现对动目标的连续跟踪。To solve the moving target＇s continuous tracking problem of the high orbit optical imaging satellite,a moving target tracking strategy using a sudoku of visual field is designed based on the consideration of the availability of visual field range and the reduction of energy consumption in attitude maneuver.This strategy can avoid the moving target lost by designing the overlap width between adjacent visual fields.The validity of the tracking strategy is verified by a simulation system which is developed in this paper.Compared to the traditional strategy which transforms the view axis of camera to the moving target when the target is outing of the visual field range,the strategy proposed can use less attitude maneuver to finish the tracking work.
