摘要
给出了光纤陀螺信号漂移的数学模型,并针对信号噪声的特点,采用了“加权求平均”、“五点三次平滑算法”、“小波分析”三种不同的处理方法进行信号的消噪处理,通过对仿真结果的比较研究,肯定了小波变换算法在信号消噪处理中的适用性,并且编写了实时信号处理软件,提高了光纤陀螺的精度,为促进光纤陀螺的研制开发起到了积极的作用。
This paper gives the model of FOG drift, and analyzes the character of signal noises. It adopts three different methods, i.e. the average algorithm of adding weight coefficient, three smoothness every five points algorithm and wavelet analysis for eliminating noises. It confirms that the wavelet analysis is applicable for signal processing, and can improves the accuracy of the FOG drift through writing program. It plays an active role in the development and research of FOG.
