基于时频分析的陀螺平台工作状态识别方法

摘要

目前惯导系统在航海、航空、导弹和宇航事业中得到了广泛应用,陀螺仪的精确度和稳定性直接决定惯性导航系统质量的好坏.阐述了陀螺平台的工作原理;对时频分析识别信号信息的方法进行了研究;给出了基于时频分析的陀螺工作状态的识别全过程.%At present, inertial navigation system is widely used in the aviation of navigation,navigation, guided missiles and aerospace cause, accuracy and stability of the gyroscope directly determine the quality of the inertial navigation system.At first, the operation principle of the gyroscope platform is explained in the paper, and then the method of time-frequency analysis which is discerned to signal information is carried on research.Finally, the whole course of the discernments of the gyroscope platform working states which is based on time-frequency analysis is put forward.
