| 摘 要： | 光纤陀螺（FOG）有着广泛地应用，如何有效地提高精度具有重要意义。根据FOG信号漂移的数学模型，分别采用了经典傅立叶分析的FIR低通滤波器和小波变换的阈值去噪对某型FOG的输出信号进行了消噪处理。实验证明了小波阈值在消除陀螺漂移和基座动态干扰应用中的优越性。

| Abstract: | Fiber-optic gyro(FOG)is used more and more wildly,so it is highly significant to increase the precise of the FOG efficiently.Based on the model of FOG,FIR low pass filter and wavelet-based threshold-value filter,respectively,are used to eliminate the noise of FOG.The experiment proves the superiority of threshold-value filtering. |
