| 摘 要： | 设计了一种基于Allan方差的5阶样条拟合的方法,用于测定光纤陀螺的随机游走系数、零偏不稳定性、速率斜坡、量化噪声、速率随机游走等参数,并基于LabVIEW开发了可视化数据采集程序,对KVH公司生产的E.Core 2000型光纤陀螺进行测试。结果表明,该方法简化了光纤陀螺参数测试流程,提高了测试精度。

| Abstract: | Allan variance based spline fit method was designed to determine some key specifications of fiber optic gyroscopes,including random walk coefficient,bias instability,rate ramp,quantization noise,rate random walk,and so on.A visualization data collection program was developed on the basis of LabVIEW to test the fiber optic gyroscope EoCore 2000 made by KVH.The test results show that the method is good for improving the testing accuracy,and can simplify the test flow as well. |
