摘要
针对高超声速再入滑翔目标受雷达探测盲区(视距盲区、近距盲区等)影响而出现航迹断续甚至目标丢失的问题,提出“跟踪-预测-…-跟踪-预测”式连续航迹的跟踪算法.首先根据平衡滑翔和跳跃滑翔两种典型飞行方式的控制律,分别设计了这两种控制律预测方法和轨迹预测方法,并且设计了轨迹判别方法来实时判别轨迹类型;然后把轨迹预测算法用于航迹连续跟踪中,用预测数据补全实测跟踪数据缺失的航迹段,实现目标航迹的连续跟踪.仿真结果表明,该算法能在再入滑翔目标受雷达探测盲区影响下较好地解决航迹断续问题,并且具有较强的适用性.
The hypersonic reentry glide target is affected by the radar detection blind area(LOS dead zone,short-range blind area,etc.),as a result of which the flightpath is interrupted and even the target is lost.In order to solve the above problem,this paper proposes a continuous path tracking algorithm of“track-prediction-…-track-prediction”.Firstly,according to the control law of two typical flight modes of balance glide and skip glide,the paper designs the prediction method for the control law of two modes and trajectory prediction method,respectively,also designing the method of trajectory discrimination to judge the trajectory type in real time.And then,the paper applies the trajectory prediction algorithm to continuous path tracking processing,and finally uses the predicted data to complete the missing path segment of the measured tracking data to realize the target path continuous tracking.The simulation results show that the proposed algorithm can help solve the problem of target path discontinuity when the reentry glide target is affected by radar detection blind area,and it also has strong applicability.
