Abstract

Up to now, resonance isolation by means of a pulse method has been performed by the calculation of the FFT of the free elastic response of the insonified target immersed in water. We propose a new method which allows the resonance detection from the FFT of the whole backscattered signal, involving the imaginary and real part spectra and in some cases, the phase spectrum. Experiments are carried out on several targets at normal incidence. This method seems to be the appropriate one to detect the resonances in the case of a “very absorptive material/elastic material” double layered plane structure.
