Abstract
The noise situation and acoustic conditions of a water area have a significant effect on the efficiency of sonar’s functioning. Noise situation analysis and modeling are require large amounts of geospatial data processing. The task becomes complicated if the forecast for the noise situation is made for non discrete functioning sonars in the specified water area during a long period of time. This challenge can be address using the interaction of geoinformation systems (GIS), databases, and calculating models. This chapter presents approaches to noise situation modeling using a hydroacoustic calculation system based on GIS, as well as examples of noise situation modeling and acoustic field calculations for the specified water area of Beibu Gulf.
