根据激光陀螺抖动机构传递函数、抖动过锁理论、抖动加噪信号以及噪声的传递特性,研究了平稳随机调幅信号通过抖动机构的传输过程,从而确定了抖动随机噪声的理想带宽［0,0.1fd］,并通过实验进行了验证,该带宽的抖动噪声信号以及加噪后的抖动输入、输出信号均能满足通过抖动机构的传递需求,有助于进一步深刻理解激光陀螺的抖动机构特性,提高抖动控制精度。

According to the dither transfer function, noise signal characteristics, dither overlock theory and the transfer characteristics of dither noise, the input and output of the dither random amplitude modulated signal in the dither system are discussed, and the bandwidth of the dither random noise is determined. The dither input, output and noise obtained through experiments are consistent with the signal principle, which is helpful for understanding the laser gyro and improving the control method of the laser gyro.
