A parametric synthetic aperure sonar for detection of proud and buried mines
Fioravanti, Stefano; Maguer, Alain; Lovik, A. (NATO. SACLANTCEN, 1997/12)This paper describes an experimental comparison between a parametric sonar and a conventional sonar for the detection of small objects on and in, the sea bed. Two experiments were performed in France (GESMA site) in October ... -
Resonance scattering analysis by autoregressive models applied to air-filled, cylindrical, thin walled shells in water
Tesei, Alessandra; Fox, Warren L. J.; Maguer, Alain; Lovik, A. (NATO. SACLANTCEN, 1997/10)Autoregressive (AR) parametric spectral estimation of the scatterer transfer function is applied to the analysis of acoustic scattering by elastic objects. In accordance with Resonance Scattering Theory (RST), the specular ...
