Underwater Acoustics Modeler

Introduction: The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, DC is seeking an Underwater Acoustics Modeler.

Job Summary: Provide senior sponsors of passive and active sonar systems with quick-reaction modeling of acoustic system performance by environment and season. Lead and/or participate on teams conducting system assessments for current or future capabilities with particular emphasis on the acoustic performance of the systems under investigation/analysis. Participate in sea test planning and execution through evaluation of proposed operation areas and in situ measurements and analyses.


  • Conduct detailed system modeling for passive and active underwater acoustic systems in support of system assessments, acquisition programs, and engineering measurements programs to ascertain performance or potential performance of the systems being modeled. Perform acoustic modeling of transmission loss, channel response (pulse distortion), reverberation and array gain. Provide statistical modeling of shipping generated noise. Provide assessments of the acoustic performance of proposed and legacy sonar systems. (50%)
  • Use appropriate models and environmental data bases to assess acoustic systems in areas of proposed sea tests or of high operational interests. Participate in sea test planning through evaluation of proposed sites and the gathering of threat acoustic characteristics. Support dynamic modeling of proposed acoustic systems and sea-test scenarios. (10%)
  • Maintain and update models as required to meet the demands of a changing sonar business base. Maintain detailed knowledge of acoustic model development in the academic, laboratory and Navy arenas. Perform model validation by comparison of predictions with sea test measurements. (20%)
  • Brief findings and write reports for program staff, sponsors and peer review groups. (20%)
