Abstract
We studied under water target classification method using acoustic resonance spectra. We interested in cylindrical shell shape targets which have different inside materials such as solid, gas and liquid. Acoustic shock wave is insonified to cylindrical shell in laboratory water tank and receive backscattering signal. Receiving signal can divide specular echo and elastic echo. The elastic echo is caused by resonance scattering and we obtain frequency spectrum of this part forclassifying used cylindrical targets. Through this study, we can decide target radius and thickness. cylindrical shell in laboratory water tank and receive backscattering signal.
