摘要
针对反导预警作战过程中远程预警相控阵雷达(early-warning radar,EWR)和多功能地基相控阵雷达(ground-based radar,GBR)探测跟踪弹道导弹的交接班问题,提出了一种可行的雷达交接班时机选择方法。该方法通过卡尔曼滤波对弹道目标进行滤波定轨,基于目标瞬时运动状态估算目标剩余飞行距离,并依据GBR对目标的探测定位精度(geometrical dilution of precision,GDOP)进行接班时机优选,以支持反导预警作战雷达交接班决策。最后,通过一个实例验证了该方法的可行性和有效性。
To solve the mission shifting problem between EWR and GBR during tracking a ballistic missile, a feasible radars mission shifting occasion selection approach is proposed. In this approach, firstly the filtering and orbit determination are realized by Kalman filter; secondly, based on the target＇s instantaneous motion state, the left flight distance of missile stays within the EWR＇s detection range is e-valuated; thirdly, GDOP of GBR is led in as the optimized reference to select the radars mission shifting occasion. Finally, an example is designed to prove the feasibility and effectiveness of this approach.
