SEALAB

The Synthetic Environment Acoustics LABoratory (SEALAB) is a comprehensive sonar simulation toolbox which ties together a wide array of acoustic models, including acoustic propagation models, target scattering, ambient noise, and reverberation. Among its discriminators from the competition are:


  • Design of experiments
  • Data analysis
  • Algorithm development
  • System performance
  • System design
  • System acquisition
  • Virtual manufacturing and testing
  • Operational environmental assessment
  • Mission planner for ASW surveillance
  • Sensor operator training
  • Optimal sensor deployment

SEALAB

The full SEALAB is developed under Unix. The computational codes are platform-independent to the greatest extent possible. Derived packages for specific problems can be targeted for any platform, and can be interfaced with MATLAB.

~~~

All of the customized computational codes within SEALAB and its derivatives are open source and are tested under the GPL (GNU Public License). Some of the underlying acoustics packages, which are only necessary for specific problems, have additional licenses.

~~~

The plotting module allows the user to seamlessly display the scenario, bathymetry and soud velocity profile. The output format of element time series can be in ascii, binary, or MATLAB.
