| 摘 要： | 在定义了光纤陀螺零偏和零漂基础上，分析了几种小波消噪算法的特点，对光纤陀螺信号进行了处理，并根据不同小波基滤波的效果，提出了一种较适合工程实际的滤波方法，同时和自适应滤波结果相比较．结果表明，采用小波滤波优于自适应滤波，而且Hair小波基的效果也优于Db4小波基．

| Abstract: | Based on the definition of zero bias and zero drift in the fiber optic gyro (FOG),several de-noising algorithms on wavelet analysis are analyzed and the signal of FOG is processed. According to the results using several different basic wavelets, a method fitting engineering practice is proposed and in the meantime the result of the method is compared with the result of adaptive filtering. |
