摘要:
光纤陀螺Allan方差零偏不稳定性表征陀螺1/f噪声或环境引起的其他低频漂移,并影响陀螺在系统中的应用性能。因此,分析Allan方差零偏不稳定性就具有重要意义,对Allan方差零偏不稳定性进行理论分析和试验验证,在理论分析的基础上采用了提高Allan方差零偏不稳定性的技术措施,测试结果表明,技术措施明显提高了高精度光纤陀螺Allan方差零偏不稳定性。

Abstract:
Fiber optic gyro Allan variance bias instability characterizes 1/f noise and low frequency drift caused by environment,also affect the application performance of gyroscope when it used in system.Therefore,the analysis of Allan variance bias instability has great significance.This article has carried on the theoretical analysis and experimental verification of Allan variance bias instability,based on the analysis of the theory put forward the technical measures to improve the bias stability of the Allan variance bias instability.The fog which used the technical measures is tested,the test results show that the technical measures significantly improve the Fiber optic gyro Allan variance bias instability.
Key words:  Fiber optic gyro  SHUPE bias errors  Allan variance
