Software Architecture on the Modeling and Simulation for Underwater Acoustics Information Systems

The simulation of underwater acoustic information flow is an important way to research sonar performance and its engagement effectiveness in the ocean environment. The significance of modeling an open and sophisticated architecture of the simulation software by object-oriented methods was analyzed, and the modeling processes and the way to represent the simulation architecture were presented. According to the requirements about the simulation system and the information flow, the simulation software logical architecture was modeled by object-oriented method. The use case view captures the system requirements. The logical view shows the logical architecture for the system. The simulation software was decomposed into its constituent parts logically by layering and package partitioning for the maintainability. Applying the design patterns, the simulation software may be well expansible and reusable. The simulation system involving multi-targets and multi-sonar was developed based on the architecture model. Practices show that the model meets the needs for simulating an open and sophisticated system.
