摘要
针对应急条件下的成像观测任务,考虑卫星成像条带切换时间等约束建立成像任务调度模型,以最小化完成测绘任务时间为优化目标。通过改进蚁群算法进行求解,结合实际约束、加入任务执行间隔等因素来控制转移概率。为地面运管系统提供了一种新的成像策略优化目标,能够根据不同的测绘任务以及用户需求,选择优化方案对实际卫星测绘做规划。
Aiming at solving the mission planning problem tions, by considering the constraints such as switching time of the objective considered is minimized to complete imaging task of satellite imaging under emergency imaging strips to establish scheduling condimodel, time in this paper. In addition, an improved ant colony algorithm is used to solve this problem. A new optimization objective is provided for ground transportation management system, which can select different optimization schemes for satellite imaging according to users＇ requirements.
