The sound reflection in specular direction on a rough surface

不平整水面的镜向声反射

In the case of primarily in the product's surface increases the specular and diffuse reflectance.

A factor representing the degree of specular reflection of a road surface.

表示道路表面镜面反射程度的因子.

In high frequency range, the specular reflection echo have the same wave form as the incident wave, but in low frequency range or resonance scattering range, there is a time expansion of the pulse width after main reflecting echo from smooth curvature surface.

在低频或谐振散射区域，光滑曲率表面的脉冲镜反射回波特征是在主回波后有时间扩展，它是由曲率反射面产生的，称为回波的曲率效应；
