中文摘要：
为实现弹道导弹精确落点的快速预报,提出基于轨道根数交接的落点预报方法。多功能地基相控阵雷达通过综合自身计算的目标轨道根数信息与远程预警相控阵雷达上报至预警中心的目标轨道根数信息,对弹道导弹实时定轨,待落点误差精度满足要求后,进行落点精确预报。仿真结果表明,相对传统落点预报方法,能够将预报时间缩短近40%。
英文摘要：
In order to estimate the impact point for ballistic missile rapidly, an impact point estimation method is proposed based on orbital elements handover. There are two kinds of orbital elements. One is computed by ground based multi-function phased array radar and the other one comes from warning center provided by long-range early warning phased array radar combined for precise orbit determination. The precise impact point can be offered if the impact point error accuracy is satisfied. The simulation results show that compared with traditional method, the proposed method can shorten the period of the predictable time by 40%.
