  • Stanton, Timothy K.; Chu, Dezhang (Acoustical Society of America, 2008-07)
    When calibrating a broadband active acoustic system with a single standard target such as a sphere, the inherent resonances associated with the scattering by the sphere pose a significant challenge. In this paper, a method ...
  • Foote, Kenneth G.; Francis, David T. I.; Atkins, Philip R. (Acoustical Society of America, 2007-03)
    The problem of calibrating parametric sonar systems at low difference frequencies used in backscattering applications is addressed. A particular parametric sonar is considered: the Simrad TOPAS PS18 Parametric Sub-bottom ...
  • Foote, Kenneth G. (Acoustical Society of America, 1982-03)
    An operational definition of backscattering cross section is developed for the wideband reception of finite echoes. This is supported by relative measurements on a set of copper spheres by each of four echo sounders operating ...
  • Foote, Kenneth G.; Chu, Dezhang; Hammar, Terence R.; Baldwin, Kenneth C.; Mayer, Larry A.; Hufnagle, Lawrence C.; Jech, J. Michael (Acoustical Society of America, 2005-04)
    Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely ...
