    • Alternative approach to passive sonar 

      Zimmer, Walter M. X. (NATO. SACLANTCEN, 1987/10)
      An alternative approach to spatial processing for passive sonar is proposed and discussed. It is

    • High-resolution beamforming techniques performance analysis 

      Zimmer, Walter M. X. (NATO. SACLANTCEN, 1986/11)
      Seven different beamforming techniques (including both conventional and high-resolution types) have been analyzed and compared in order to develop a quantitative relationship between resolution performance on the one hand ...

    • Logarithmic least mean square sound-field estimation 

      Zimmer, Walter M. X. (NATO. SACLANTCEN, 1987/03)
      The report deals with narrowband beamforming techniques for passive sonar applications. In particular, the Least Mean Square fit parameter estimation technique is used to estimate the spatial sound-field power density. To ...

    • Multiple beamforming 

      Zimmer, Walter M. X. (NATO. SACLANTCEN, 1985/07)
      Beamforming techniques are generally based on the assumption that the received signal arrives from
