潜射导弹初始误差与制导工具误差分离研究

Research on Separation of Initial Error and Guidance Instrumentation Error in Submarine Launched Missile

首先分析了发射初始误差对导弹落点偏差的影响机理,然后利用初始误差在发射惯性系中的传递关系得到了初始误差环境函数矩阵,建立了综合考虑初始误差与制导工具误差的完整误差分离模型,并提出了一种分时间段的误差分离方法。此外还讨论了遥外差信息的选取原则。

This paper firstly illustrates the influence of initial error when launching on points of fall of missile. Secondly, the paper derives initial error environment function matrix from the transfer relation about initial error in launch-inertial coordinates. Considering initial error and guidance instrumentation error synthetically a full model of error separation is constructed, and then a corresponding calculational method based on time intervals is presented. Also the technique in terms of selecting telemetry-tracking deviation information is discussed.
