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 ... -
Sub-bands beam-space adaptive beamformer for port-starboard rejection in triplet sonar arrays
Stinco, Pietro; Tesei, Alessandra; Maguer, Alain; Ferraioli, Fabrizio; Latini, Valerio; Pesa, Luca (CMRE, 2019/05)This paper addresses the problem of Port-Starboard (PS) beamforming for low-frequency active sonar (LFAS) with a triplet receiver array. The paper presents a new algorithm for sub-bands beam-space adaptive beamforming with ... -
Tank measurements of elastic scattering by a resin-filled fiberglass spherical shell
Tesei, Alessandra; Guerrini, Piero; Canepa, Gaetano (NURC, 2007/12)Acoustic elastic scattering measurements were conducted in a tank on a 6cm radius fibreglass spherical shell filled with a low-shear-speed epoxy resin. Preliminary measurements were conducted also on the void shell before ... -
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 ...
