摘要
光纤陀螺以其全固态、无转动机构、高集成性,较宽的动态测量范围等优点逐渐成为陀螺发展的趋势。光纤陀螺所敏感的角速度信号中包含有各种噪声误差,如何对光纤陀螺输出信号进行处理以满足不同的工程应用要求是目前研究的关键问题。本文对中低精度的光纤陀螺在运动条件下的测量信号进行滤波处理,通过实测数据的应用验证,该方法能够有效减小信号方差且能保证滤波信号实时性。
With the advantage of full-solid state, non-motor, high-integrated, wider dynamic measurement scope, the Fiber Optic Gyro （FOG） has being the development trend of gyro. It almost sends out angle rate in digital style. It＇s important to research how to filter the output signal of FOG. In this paper, a digital filter has been mentioned to filter the output signal of FOG which used in dynamic surrounding. Proved by actual application, the means can reduce the variance of signal efficiently and keep filtered signal track in time.
