| 摘 要： | 提出一种针对星载定向链路的多目标优化设计方法。定向链路的优化设计过程是一个多目标优化的过程,要求定向链路在质量、功耗等条件的约束下,尽量满足飞行任务对其功能的需要。文中首先建立定向链路各分目标函数的数学模型,然后根据卫星任务的需求为各分目标函数分配权重,最后通过统一目标法将各分目标函数组成一个统一目标函数,并对统一目标函数进行优化,进而实现对定向链路的优化设计。

| Abstract: | This paper studies on the multi-objective optimization method of directional link system of satellite.A method of multi-objective trade-off for directional link system is proposed to maximize the quality of telecommunication with the minimized cost,which involves mass,power,and so on.Mathematical models for components of directional link system are established.Then each one is assigned a weight coefficient to compose a union objective function which is the object of multi-objective optimization for on-board... |
