摘　　要：针对敏捷遥感卫星突发多目标观测任务的在轨实时规划问题,提出一种面向在轨实现的启发式前后向链条优化组合方法。该方法以敏捷卫星滚动俯仰两个自由度的姿态机动能力为输入,设计了一种基于高权重组链、以姿态机动能力结合观测收益合成链条的启发式方法。完成了不同机动能力下的蒙特卡罗打靶仿真,优化了链条选择策略,获得了较高的观测收益。实验证明所提方法有效,观测收益高,计算开销小,可应用于敏捷卫星面向大量点目标的在轨自主任务规划。Aiming at the on on-board real-time planning problem of multi-objective observation task for agile remote sensing satellite,a heuristic optimized forward-backward chain combination method for on-board implementation is proposed.In this method,the attitude maneuver ability of agile satellite with two degrees of freedom of rolling and pitching is taken as input,and a heuristic method based on high weight group chain and combining attitude maneuver ability with observation revenue is designed.The Monte Carlo simulation under different maneuverability is completed,the chain selection strategy is optimized,and higher observation revenue is obtained.Experiment shows that the proposed method is effective,has high observation revenue and low computational cost,and can be applied to the on-board autonomous mission planning of agile satellites for a large number of point targets.
