抖动激光陀螺幅度随机噪声概率分布的K检验

Test on Probability Distribution of Amplitude Random Noise Mechanically Dithered RLG

为了消除抖动偏频激光陀螺仪的动态闭锁误差,需要向正弦抖动信号中注入一具有平稳性的随机噪声,以使抖动幅度随机变化。本文对机械抖动偏频激光陀螺仪抖动加噪的物理可行性进行了理论分析,用 K检验法证明了所设计的抖动噪声发生器产生的随机噪声服从高斯概率分布,满足抖动噪声注入的要求。

To eliminate dynamic lock-in error of Mechanically Dithered ring laser gyroscope,it is desirable to inject a pseudo smooth random noise into the sine wave dither signal.Analyses the principle of dither noise injection,designs a dither noise generator.It is approved that the dither noise injection method can assure that dither noise follows the Gauss probability distribution (?)K test.The result shows that the dither noise produced by the dither random noise generator can eliminate dynamic lock-in error.
