飞行体姿态惯性测量技术综述

Overview on Inertial Measurement Technology for Flight Attitude of Missile

为了研究弹道修正查阅了大量的惯性测量技术相关文献,收获颇丰。为了使读者也对惯性测量有较全面了解,特作综述。读者可从单种惯性器件测量技术及惯性测量组合技术两方面着手研究。从最早的刚体转子陀螺仪发展为光纤陀螺仪,从六加速度计组合发展为目前较为广泛使用的九加速度计组合,无论单陀螺仪组合还是单加速度计组合都无法克服本身所固有的性能缺陷,如测量精度低、成本高、性能差;而不同惯性测量组合技术的提出,正是弥补了这一缺陷,它基于信息融合的技术,利用多种测量器件性能互补的特性,提高了测量精度,降低了成本、改善了性能。

To study trajectory correction,we looked up amount of documents on inertial measurement technology,and had learnt a lot from that.The purpose of the overview is to help readers have a comprehensive understanding of inertial measurement technology.It is suggested that readers start their research with single inertial devices measurement technology and combined inertial measurement unit technology.From early rigid rotor gyroscope to fiber optic gyroscope,from six accelerometers to nine accelerometers which is widely used now,whichever measurement units can＇t overcome its inherent defects,such as poor measurement accuracy,high cost or poor performance,etc.Combination of different inertial measurement unit techniques may make up for those defects,which based on information fusion technology and complementary characteristic of different inertial devices,which could increase measurement precision,reduce cost and improve performance.
