Random walk analysis of fiber optic gyroscope

  • 摘要: 光纤陀螺测试中,随机游走系数的分析对陀螺整体性能的评价起着很重要的作用。分别介绍了分析光纤陀螺随机游走噪声的两种方法:Allan方差法和改进的Allan方差法。分别应用这两种方法,在对某型光纤陀螺(FOG)实测静态数据计算的基础上进一步分析了该光纤陀螺中的噪声分量,并对分析结果进行比较。最终计算结果表明:在增加计算时间为代价的前提下,改进Allan方差法能方便地区别出各种噪声,并明显提高了光纤陀螺各随机噪声游走系数的计算精度。
    Abstract: The analysis of random walk coefficient is very important to the overall performance evaluation of fiber optic gyro (FOG). Two methods were introduced to analyze FOG random walk noise, Allan variance and modified Allan variance. Static data were used to calculate the noise contents in fiber optic gyroscope (FOG)s output with these two methods, and the results were compared. The final results show that modified Allan variance can distinguish all types of noise easily with increased computation time and the computation accuracy of the various FOG random walk noise coefficients can be improved.
