| Abstract: | 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. |
