An Object-Oriented Application Framework For The Simulation Of Underwater Acoustic Field

Based on the study of underwater acoustic field, this dissertation summarizes the structure characteristics of various propagation models, such as Normal Model, Ray Model etc., establishes the object model of domain, designs and develops the Object-Oriented Application Framework for Underwater Acoustic Field Simulation (OOAFS). The application framework is based on MVC (Model/View/Controller) pattern. Using Design Pattern and Component techniques the extensibility, reusability and flexibility of the application framework are improved.A prototype software for acoustic field simulation has been developed. Some application examples are illustrated in typical ocean environment conditions, which verified the validity of the application framework.The response of ocean channel and the response of a tow line array to the noise from the tow ship have been studied by extending the function of the OOAFS in this dissertation, and a part of the results have been successfully recognized as an important reference for a tow line array sonar system.Advanced software engineering approach and implementation techniques have been applied in the research. Therefore, the major results obtained by the author are original in this application domain. The OOAFS is maintainable, extensible and reusable. It provides a new and powerful means for the modeling and simulation of acoustic field. The architecture and idea of the OOAFS is suitable for the underwater acoustic field simulation, and also can be expanded into other simulation systems in the underwater acoustic domain. Meanwhile, the dissertation provides a new methodology for the specified domain.
