水声信息系统仿真是研究声纳及其水下作战效能的重要工具。针对仿真软件系统的复杂性与开放性的特点，分析了利用面向对象的方法建立其软件构架模型的意义，并介绍了软件构架建模过程和表示方法。根据仿真系统功能需求和海洋声信息环境特点，采用面向对象方法，提出了仿真软件系统的逻辑构架。由用例视图描述需求，逻辑视图描述逻辑构架。通过分层与包的分解，将仿真软件从逻辑上划分成松耦合的多个组成部分，以便于系统维护。设计模式的运用，使得仿真软件具有很好的重用性和扩展性。基于构架模型，实现了由多目标与多声纳构成的水声信息仿真系统。实践表明，该构架模型满足开放性与复杂性系统的仿真要求。
Abstract
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 arcmtecture 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 arcmtecture was modeled by ooject-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 parti?tioning for the maintainability. Applying the design patterns, the simulation software may be well ex?pansible 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.
