At-sea measurements of acoustic elastic scattering by a 1.5m-long cylinder made of composite materials
Tesei, Alessandra; Zampolli, Mario; Canepa, Gaetano (NURC, 2007/12)Monostatic and bistatic acoustic scattering measurements were performed on solid-filled fibreglass objects (a sphere and a cylinder with hemispherical endcaps) deployed proud on a sandy seabed and insonified by a rail-mounted ... -
Measurements and modelling of high-frequency acoustic scattering by a rough seafloor and sea surface
Tesei, Alessandra; Canepa, Gaetano; Zampolli, Mario (NURC, 2009/12)Acoustic scattering by a rough, possibly dynamic interface is experimentally studied by insonifying the seabed and the sea surface at high frequency at various incidentangles. A directional source working at 300 kHz was ... -
Review of target strength information for waterside security applications
Zampolli, Mario; Jensen, Finn B.; Tesei, Alessandra (NURC, 2008)Estimates of the target strength of objects, such as for example scuba tanks and swimmer delivery vehicles, are parameters of interest in all phases of the design of waterside security systems. Results of numerical target ... -
Tank measurements of scattering from a resin-filled fibreglass spherical shell with internal flaws
Tesei, Alessandra; Guerrini, Piero; Zampolli, Mario (NURC, 2008/09)This paper presents results of acoustic inversion and structural health monitoring achieved by means of low to midfrequency elastic scattering analysis of simple, curved objects, insonified in a water tank. Acoustic elastic ...
