摘　　要：文章对光纤陀螺仪的实测信号进行了分析。为了抑制光纤陀螺随机噪声,利用五点三次平滑、数字滤波、小波变换分析法对光纤陀螺静态输出数据进行了滤波处理,通过对比滤波前后陀螺的输出曲线、标准差以及频谱图,可以发现:小波阈值滤波和五点三次平滑相结合的方法能够有效的补偿光纤陀螺的随机误差。Fiber Optic Gyro measured data from experiments was analyzed in this paper.In order to restrain the Fiber Optic Gyro random drift,filter was carried on using three smoothness every five points smoothing method, digital filter and the wavelet analytic method to the Fiber Optic Gyro static output,through contrasting around the fiber-optic gyro output curve,the standard deviation as well as spectrum graph,it can be discovered that wavelet threshold filter combined three smoothness every five points smoothing method compensated effectively the fiber-optic gyro random error.
