功率谱估计在光纤陀螺信号处理中的应用

The Application of Power Pectrum in the Processing Signal with FOG

文中介绍了采用功率谱估计的方法估计光纤陀螺的噪声,采用多抽样率算法对光纤陀螺信号进行滤波处理。并将此算法在 DSP 中实现。采用此种滤波方案,可以有效的保证陀螺有用信息不产生混叠失真,从而提高光纤陀螺的测试精度。

The implementation for the yawp in FOG with the estimate of power spectrum,using multi-rate digital pro- cessing disposal the FOG signal.We realized the method with digital signal processor.In this implementation the FOG processes lower zero drift and higher sensitivity.
