区域机动目标普查监视小卫星组网设计与仿真

Satellite constellation design for regional maneuvering target searching

针对海洋机动目标任务规划难、搜索难度大的特点,设计了一种面向海洋热点区域机动目标搜索监视的卫星组网星座。首先,根据机动目标搜索任务的特点,建立考虑时空约束条件的卫星成像条带拼接搜索策略;其次,根据机动目标搜索策略,设计了一种高时间分辨率组网星座构型;最后,构建以最小组网卫星侧摆角度和任务观测时间为优化目标的鲁棒模型,采用遗传算法对组网卫星进行优化求解,并给出算法实现流程。仿真结果表明,该卫星组网星座能够有效完成对目标区域机动目标覆盖监视,为热点区域海洋机动目标监视任务提供了一定的方法支撑。

Aiming at imaging satellite mission planned for marine maneuvering target,a satellite constellation for maneuvering target in ocean area searching and monitoring is designed.Firstly,according to the characteristics of maneuvering target search task,a satellite image stitching search strategy considering spatio-temporal constraints was established.Secondly,according to the established maneuvering target search strategy,a high time resolution networking constellation configuration was designed.Finally,a robust model was constructed based on minimizing the side pendulum angle and the task observation time of the networking satellite as the optimization target.The simulation results demonstrate that the satellite constellation can effectively monitor the target area,providing the support method for maneuvering target regional surveillance task.
