摘　　要：高超声速滑翔飞行器在再入过程中除了需要满足热流、过载、动压过程约束外,还需要满足航路点以及禁飞区的路径约束。路径约束可以是发射前装订的,也可以是实际飞行中由导航卫星、预警雷达等在线探明的敌方防御区。针对再入过程中存在在线探明禁飞区的再入制导问题,设计了解析倾侧角剖面以满足再入轨迹航程约束,引入预测校正算法修正倾侧角剖面,并基于人工势场法设计了侧向制导方法以满足在线探测到突发威胁而形成的多路径约束。仿真结果验证了该算法能够有效解决存在突发威胁的多路径约束再入问题。In the process of reentry,in addition to constraints of heat flow,overload and dynamic pressure,the hypersonic glide vehicle also needs to satisfy path constraints of waypoints and no-fly zones.The path constraints can be preset before the launch.During the flight,no-fly zones can be enemy defensive zones detected by navigation satellites and early warning radars.Aiming at the reentry guidance problem with sudden threats detected in the reentry process,an analytic bank angle profile is designed to satisfy a trajectory range constraint,and the predict-correct algorithm is introduced to amend the bank angle profile.The lateral guidance is based on the artificial potential field method to satisfy the multiple path constraints with sudden threats.Simulation results verify that the algorithm is able to solve the reentry guidance problem with multiple path constraints.
