| 摘 要： | 巡天扫描是天文卫星进行天体观测的基础,但是使用传统方法很难实现全天球覆盖,并且会遇到能源输出瓶颈。因此,本文针对天文卫星巡天扫描所遇到的问题,提出了使用基于实值编码的遗产算法(Real-codedGA)对卫星飞行任务进行智能规划的方法。该算法智能规划飞行任务,与仅依靠被动的分段式扫描方法相比,很好解决了能源输出的问题,还大大缩短了巡天扫描的时间。从仿真结果来看,该模型是十分有效的。

| Abstract: | Scanning the celestial sphere provided a base to satellites' celestial bodies observation.But there were two problems which were difficult to solve: one is how to scan the whole celestial sphere; the other is power output is not enough sometimes. An intelligen- tized controlling method using real- coded genetic algorithm was brought forward which could scheme the satellite' s flight mission. Compared with the passive zoning method, this model has two advantages: the power outputting is increased though scheming the satellite ' s flight mission and the time of scanning the celestial sphere is decreased. Simulated experiment shows that this model is efficient. |
