| 摘 要： | 在凝视扫描系统中,大惯量反射镜与快速控制反射镜的速度匹配非常重要。陀螺的输出噪声影响两者的速度匹配,于是陀螺输出信号的滤波就成了首要的问题。通过对三种滤波方法的研究,结果表明:小波收缩去噪具有更好的信噪分离效果。

| Abstract: | The speed matching between big-inertia mirror and fast-steering mirror is very important in staring and scanning system.The output noise of the gyro has direct effect on the speed matching,thus the filtering of the output signal of gyro becomes the most important.We studied three filtering methods,and the simulation result indicated that wavelet shrinking de-noising has the best effect on separating signal from noise. |

| Keywords: | flexible gyro staring and scanning FSM mean method of preventing disturbance by impulse wavelet filtering |
