RV Bat Galim 2016 Acoustic Test Report

During the at-sea test on BAT GALIM, the main objective was to determine ship acoustic characteristics and to assess potential impacts to sonar performance from all acoustic sources. The primary sonars of interest were the newly installed Kongsberg EM 302 and EM 2040 multibeam systems. The following evaluations were accomplished as part this testing:
  1. The overall noise levels of BAT GALIM were measured and characterized with special test sensors and internal noise routines inherent in the Kongsberg sonars.
  2. Propeller cavitation characteristics were assessed.
  3. Shallow water measurements were conducted to determine the impact of bottom bounce acoustic noise on sonar systems.
  4. Sonar interference testing was conducted to determine impacts of multibeam, ADCP and sub-bottom profiling sonars.
