一种考虑禁飞圆约束的在线再入弹道规划方法

An On-board Reentry Trajectory Planning Method with No-fly Zone Constraints

采用基于航向误差走廊的横向机动策略绕飞禁飞圆,满足过程约束的同时也使得包含速度倾角在内的其它终端状态参数满足约束条件。飞行过程中实时进行弹道更新,提高跟踪精度的同时,也使得再入飞行器初步具备了飞行过程中自主变换打击目标的能力。仿真结果表明,给出的规划方法能实时规划出满足约束的再入弹道,以较高的精度到达再入段终点的同时具有较好轨迹特性。

The use of transverse maneuver strategy based on heading error corridor meets the process constraint requirements. So do other terminal state parameters. Trajectory updating in flight enhances the tracking accuracy and enables the reentry vehicle to switch attack target autonomously. Simulation results demonstrate that the proposed method can not only conduct an on-board real-time trajectory planning satisfying both path and terminal state constraints, but also reach the end point in good condition.
