摘要
对逆M序列在消除激光陀螺动态闭锁误差中的应用进行了研究和验证。目前多采用M序列对抖动的幅度进行调制来消除激光陀螺动态闭锁误差,而逆M序列与M序列相比不仅满足注入到激光陀螺抖动中的要求,且比M序列有其性质等方面优势。通过理论分析及M序列和逆M序列在消除机抖激光陀螺动态闭锁中实验中的应用对比,实验数据表明逆M序列在消除动态闭锁中的作用要优于M序列。
To eliminate dynamic lock-in error in mechanically dithered ring laser gyroscope (MDRLG), inverse M sequence is analyzed. Nowadays M sequence is used mainly to inject into the dither signal, and the dither amplitude is stochastic. The injected pseudo-random noise (M sequence) is changed into pseudo-random noise (Inverse M sequence) to eliminate dynamic lock-in error, and it is better than M sequence.
