摘要
本文采用一种新的规一化方法,对五种粗糙度不同的表面进行了超声背向散射系数的测量,给出了平均散射声强与物体表面粗糙度,超声频率和接收掠射角之间的变化关系,并与理论结果进行了比较。
In this paper, adopting a new normalized method, the ultrasound backscattering coefficient from five kinds of rough surfaces is measured. The relation of the mean scattered sound intensity as a function of surface roughness, ultrasound frequency and receiver grazing angle is given. The resulls are compared with the theory (see another paper). They agreed very well.
