直升机超视距主动引导定位误差分析

针对用直升机引导超视距导弹攻击目标的需求,对直升机超视距引导定位的误差来源进行探讨,利用微分原理求解三角形误差的方法,建立惯导大地法、航姿大地法、双向定位法三种不同引导定位方法的误差求解模型。利用误差来源数据进行编程解算模型,最后得出定位误差分析结论,为舰载反舰导弹精确超视距攻击提供有益的参考。

Analysis on OTH Active-Guiding Positioning Error for Helicopters

According to the demands which make helicopter as a platform to give guidance for over-the-horizon (OTH) missiles attacking targets, this paper discusses the positioning error sources when a helicopter is operating OTH guidance. By solving the triangle error with differential theory, it sets up error solution models with three different methods including inertia-navigation, navigation-pose and bi-orientation positioning. Calculating the error models with programming of the error sources, a conclusion of error analysis is educed. The results will be good reference for ship-to-ship missiles in OTH attacking operation.
