摘要: 提出了多颗成像卫星对某一区域目标进行观测的侧摆方案优化方法。该方法主要包括调度预处理与优化两个步骤。在调度预处理阶段,集成STK软件解决了航天观测中时间窗口难以量化计算等问题;在优化阶段,建立数学优化模型,并基于遗传算法实现了模型的求解。Abstract: An elevations selection approach of area target surveillance task using multi-satellites is presented.The approach includes two stages: pretreatment and optimization.In the pretreatment stage,STK is applied to solve the difficult problem of computing access time;in the optimization stage,models and solving method based on genetic algorithm is presented,and a scenario instance proves the validity of the method.
