Array performance and variability at short range near Vestfjorden
Del Balzo, Donald R. (NATO. SACLANTCEN, 1993/08)An experiment was conducted in October 1989 in shallow water near Vestfjorden in support of low frequency active sonar system research at SACLANTCEN. This report addresses some acoustic measurement results from that test ... -
Critical angle and seabed scattering issues for active-sonar performance predictions in shallow water
Del Balzo, Donald R.; Leclere, James H.; Collins, Mona J. (NATO. SACLANTCEN, 1997)Active sonar performance predictions (0.75 to 3 kHz) are examined in summer shallow-water environments to quantify the impact of variable seabed and watermass properties on detection. Scattering is computed with an ... -
Random temperature structure as a factor in long-range propagation
Del Balzo, Donald R.; Moseley, W. B. (NATO. SACLANTCEN, 1975/10)A statistical description of horizontal thermal microstructure in anosotropic turbulence is developed for application with an existing acoustic propagation theory. The model predicts a temperature power density spectrum ...
