机抖激光陀螺仪过锁区误差分析

Analysis of Lock-in Error for Mechanically Dithered RLG

文中在理论上分析了抖动偏频激光陀螺仪标度因数误差与闭锁阈值、抖动偏频量的关系,并用Matlab 对其关系进行了仿真计算,验证了激光陀螺仪输入角速率在抖动偏频量附近由抖动偏频造成的标度因数非线性最为严重、速率测量误差最大的结论。

This paper analyses the relation of scale factor error of mechanically dithered ring laser gyroscope and lock- in or dither depth,simulates by Matlah,validates the conclusion that when input angle velocity is equa] to dither depth that scale factor error is most serious and angle velocity measurement is most.
