Abstract :
The purpose of this study is to highlight effects of a set of periodically spaced rings on the acoustic scattering from a finite cylindrical shell. The air-filled target immersed in water, is investigated thanks to the monostatic configuration. Experimental results are discussed in the angle/time and angle/frequency spaces.
