针对空间目标光电跟踪调度问题,根据不同轨道空间目标的运动特征,着重考虑对编目定轨影响最大的轨道弧长,基于线性规划模型,分别提出了适合低轨道和中高轨道空间目标跟踪调度优化数学模型。仿真计算表明,模型在消除弧段冲突、充分利用观测时间的基础上实现了最优轨道弧长的观测策略,计算量适当,能够满足实践应用的需求。实测试验表明调度策略有效可行,能够提高50%的有效观测时间。
According to the motion characteristics of different orbital space targets, considering the trajectory arc length which has the most influence on the orbital orbit determination, based on the linear programming model, the optimization maths for low orbit and middle and high orbit space target tracking and scheduling optimization math model. The simulation results show that the model achieves the optimal orbital arc length observation strategy by eliminating the arc conflict and making full use of the observation time. The calculation is suitable and can meet the needs of practical application. Experimental results show that the scheduling strategy is effective and feasible, which can improve the effective observation time by 50%.
