摘　　要：航天返回器的再入阶段,因为返回器出黑障后轨道低、角动态极高、可观测弧段很短,此时若采用传统的机械轴跟踪目标的方式,存在跟踪超调大、收敛慢和接收遥测数据较晚等缺点。为解决这一难题,提出并实现了一种电波束、机械轴综合捕获方法,用于实现返回器的快速捕获稳定跟踪。应用结果表明,这种快速捕获跟踪方法超调小、收敛快速,同时还可以提高单站的测控时间。Ionization blackout may happen to near space flight vehicles flying at sonic speed,thus poses a tremendous challenge for antenna acquisition and tracking. To address the challenge,an acquisition and tracking method combining mechanical axis and electric beam modes based on digital multi-beam is proposed,which can meet the requirements for fast acquisition and stable tracking of the reentry capsule. The application results show the fast acquisition and tracking method can realize fast convergence and stable tracking,and also improves the tracking time for every telemetry station.
