惯性制导工具误差分离技术综述

Review of inertial guidance instrumental error separation techniques

惯性制导工具误差分离是验证惯性制导系统天地一致性和导弹武器精度鉴定试验的关键环节,为导弹武器的精度评估和后续改进提供重要支撑作用。传统弹道导弹所用平台式惯导系统的工具误差分离问题已经被充分研究,新型惯导设备的发展以及高超声速飞行器等新型装备的发展需求,对惯性制导工具误差分离提出了新的挑战。本文从发射条件、所需要素和惯导模式3个方面分析了惯性制导工具误差分离的发展现状和特点,对新需求下的发展趋势进行了分析和展望。

Inertial guidance instrumental error separation is the key to verify the space-ground consistency of inertial guidance systems and the accuracy identification test of missile weapons,which provides important support for the ac⁃curacy assessment and subsequent improvement of missile weapons.Although the problem of instrumental error separation of platform inertial guidance systems used in traditional ballistic missiles has been fully studied,with the de⁃velopment of new inertial guidance devices and the development requirements for hypersonic vehicles and other new equipments,new challenges have been posed for inertial guidance instrumental error separation.This paper analyzes the development status and characteristics of inertial guidance instrumental error separation from three aspects:launch conditions,required elements and inertial guidance mode.Besides,it analyzes and prospects the develop⁃ment trend under new requirements.
