| 摘 要： | 在介绍小波分析理论的基础上,本文采用双正交静态小波基对陀螺仪去漂后的残差信号进行不同尺度的分解.通过不同小波基滤波效果的比较,发现双正交样条小波具有较好的去噪性,其分解和重建滤波器系数也十分简单,验证了小波变换在陀螺仪测漂信号去噪中的可行性.

| Abstract: | The wavelet theory was introduced. The residual signal from the gyroscope was decomposed by the different scale biorthogonal stationary wavelet base. The result showed that the Biorl. 1 wavelet had the better performance. The coefficients of the decomposing filter and the rebuilding filter were also very simple. It proved that the wavelet transformation was feasible in the de-noising of the gyroscope drifting signal. |

| Keywords: | wavelet transform filter group gyro drift multi-resolution analysis |
