If you have them, it's definitely worth trying out a filter or two to help you control and enhance the reflection effect.
如果你做到了以上所说的，尝试使用一个或多个滤镜吧，它会帮助你控制和提高倒影的效果。

It was found that the transmission spectrum of the filter is the cosine function modulated reflection spectrum of the fiber grating.
结果表明该滤波器的透射光谱是余弦函数调制后的光纤光栅反射光谱。

The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave.
