Abstrakt: The angular dependence(profile) of backscattered ultrasound was measured for steel specimens with periodical surface roughness (1–71μm). Backward radiations showed more linear dependency than normal profile. Direct amplitude increased and averaging amplitude decreased with surface roughness. Painting treatment improved the linearity in direct backward radiation below roughness of 0.03λ. Scholte and Rayleigh-like waves were observed in the spectrum of averaging backward radiation on periodically rough surface. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
