摘要
在简述小波分析中 Mallat 算法的基础上,用其实现激光陀螺仪漂移特性的小波分析,讨论了余弦滤波器的设计。提出合适的小波对激光陀螺信号进行不同尺度的分解,在应用中得到了良好的去噪效果。
In this paper,the wavelet analyses of ring laser gyro drift rate were implemented based on the Mallat algo- rithm in the wavelet analysis,the design of cosine filter is discussed.The appropriate wavelet bring forward to analysis ring laser gyro signal.An effective filtering result is got by using this method.
