摘要: 针对导弹防御过程中高轨预警卫星与远程预警雷达的交接班过程, 对弹道误差传播与导弹预警信息表示2个问题进行了研究。分析了利用协方差分析描述函数法(CADET)对弹道误差传播的计算过程。针对误差传播的结果, 由精细到粗略提出了4种预警信息模型, 概率椭球模型、概率球模型、均匀椭球模型和均匀球模型, 利用4种模型可以计算得到不同粒度的导弹预警信息。仿真结果表明文中建立的预警信息模型可以对导弹状态进行较为完善的描述。

Abstract: Aiming at the process of transition between high orbit early warning satellites and long range early warning radars in the course of missile defense, two issues were investigated: ballistic error propagation and missile warning information representation. The calculation process of ballistic error propagation using CADET was described. For the results of the error propagation, four kinds of early warning information models, which included the probability ellipsoid model, the probability spherical model, the uniform ellipsoid model, and the uniform sphere model were proposed. The missile warning information of different granularities was calculated using the four models. The simulation results showed that the early warning information models established described the missile state more fully.

Key words: high-altitude early warning satellites, long-range early warning radars, ballistic forecasting, error propagation, state estimation, warning information
