基于动力学的弹道导弹目标轨道维持算法

An orbit maintenance algorithm for ballistic missile targets based on dynamics

在弹道导弹目标跟踪过程中会由于地形遮蔽、弹头姿态变化、雷达威力等原因出现短时间内无法检测而导致目标丢失。经重新捕获后发现丢失目标,此时若不进行目标轨道维持,则无法判断新捕获目标与之前丢失目标是否有关联,不利于整体态势显示。本文提出了弹道导弹目标轨道维持算法,对跟踪的目标航迹周期性进行轨道外推,一旦目标丢失,重新捕获后的目标需要与外推轨道进行匹配,匹配上的目标保持丢失目标的批号。通过仿真实验对弹道目标进行了验证,结果表明该算法能够实现目标轨道维持。

The target may be lost due to terrain masking, warhead attitude change and radar cover- age during the tracking of the ballistic missile targets. After the target is recaptured, if there is no target orbit maintenance, whether it is the former lost target cannot be confirmed and the overall situation cannot be well displayed. Therefore, an orbit maintenance algorithm is proposed for the ballistic missile targets. The orbit extrapolation is performed periodically for the target tracks. Once a target is lost, the target recaptured should be matched with the extrapolating orbit. If it is on the lost target＇s orbit, it still uses the same batch number. The simulation results show that orbit maintenance can be realized via the algorithm for the ballistic missile targets.
