| 摘 要： | 首先利用极零点受限自适应陷波器对二频机械抖动激光陀螺输出信号利用预处理,然后再进行低通滤波器处理的方法,不仅有效地消除了抖动输出,而且减小了由FIR滤波器引起的时间延迟。

| Abstract: | A new method of dither signal remover of the dithered ring laser gyroscope utilizing adaptive notch filter(ANF)with constrained poles and zeros to prefilter is introduced.By using ANF,the delay time of FIR filter is reduced and the remnant dither signal is removed. |
