针对红外低轨系统,综合考虑定位精度、空间覆盖以及星座成本等因素,提出了红外低轨星座的设计准则,并定义星座性能的度量指标.然后,引入GDE 3算法用于红外低轨星座设计,该方法基于Pareto最优概念,能够得到多个最优解,适于多目标优化设计.通过星座建模和目标函数设计,进行了仿真实验.最后验证了设计得到的星座在多项性能指标上均优于已有文献中的星座.
Considering the positioning accuracy, space coverage and the cost of constellation, the design criteria of infrared low-orbit constellation and the metrics of constellation performance are defined for the infrared low-orbit system.Furthermore, the GDE 3 algorithm is introduced into the design of infrared low- , This method is based on Pareto optimal concept and can obtain multiple optimal solutions and is suitable for multi-objective optimization design.The simulation experiment is carried out by constellation modeling and objective function design.Finally, the design of the constellation is validated in a number of performance indicators Are better than the constellations in the existing literature.
