Hydro acoustic calculations system is a software product designed for ray-path and wave methods based calculation of a sound energy loss in marine environment for infrasonic and sonic frequency ranges.

    The developed methodology allows calculating spatial distribution of a sound energy loss (per spreading or attenuation) accounting for a user specified environmental model, characteristics of emitting and receiving systems. 

    Application range

    Software product is designed to perform the current tactical calculations and to serve as a modeling tool for experimental and research objectives.

    Possibilities

• Well developed interactive user-friendly environment;
  
• Usage of underwater topography database of the US National Center of Geophysical Data with two angular minutes resolution (ETOPO2) and five angular minutes resolution (ETOPO5);
  
• Usage of climatologic database of sonic speed field of Word Ocean of USA Ministry of Defense (GDEM);
  
• Calculations using wave and/or ray algorithms.
