Gausian分布表面超声背向散射的研究

A Research on Ultrasound Backscattering from Gaussian Distributed Rough Surface

本文给出了Ｇａｕｓｓｉａｎ分布表面的平均背向散射声强与物体表面粗糙度，超声频率和掠射角之间的闭形解析表达式．并与Ｂｏｙｄ等报道的实验结果进行了比较。

In this paper, the mean Backscatterd sound intensity by a surface described by a Gaussian distribution of heights is calculated A formulation of the mean Backscattered sound intensity as a function of surface roughness, ultrasound frequency and grazing angle is developed. The theory is compared with experimental results in paper,they agreed very well in large grazing angle.
