【摘要】 水声电子信息图是以水声工程、导航技术、地理信息系统、计算机等多门学科为依托的应用性技术。该项技术可以把水声研究过程中所需信息及船体在航行过程中的信息以可视化的形式在电子海图中显示出来。本次设计的电子海图可接收并显示海洋环境参数、声纳参数、声纳作用距离预报结果及GPS导航参数,从而为舰艇导航、战略指挥提供一个可视化平台。本论文首先以声纳方程为基础,对影响声纳工作的声纳参数、目标参数、信道参数进行了系统的分析。在此基础上,对声纳作用距离进行了深入的理论研究,从而推导出被动声纳与在噪声掩蔽下的主动声纳的作用距离公式；然后,对导航技术及地理信息系统软件进行了一定的理论分析；分析了电子海图软件设计思想及其所要实现的功能,建立了模块化程序结构。本次软件设计分为导航信息模块、电子海图控制模块、声纳信息模块、数据库及其接口模块设计。最后,对软件进行了联调,从而实现预期功能。本设计基于Visual C++ 6.0开发平台,使用微软基础库(MFC)与MapX组件技术结合进行开发,采用开放数据库连接(ODBC)技术对数据库进行管理,并使用串口完成通信。更多还原

【Abstract】 The map of underwater electronic information is an applied technology based on underwater acoustic engineering, navigation technology, geographic information systems, computer and other subjects. The information that Underwater Acoustic research needs and the hull in the navigations can be visually displayed in the electronic chart by this technology oThe Electronic Chart in the design can receive and display the ocean environment parameters, sonar parameters, the prediction result of the sonar operating range and the GPS navigation parameters which can provide a visual platform for ships navigation and stratagem direct.Firstly, based on the sonar equations, the paper analyzed the sonar parameters, the target parameters and the channel parameters which affect the work of sonar systemically. Based on this, made a further theoretical study on the sonar operating range, and figured out the operating range formula of the passive sonar with the active sonar under noise masking. And then, made some theoretical analyze on the software of navigation technology and Geographic Information System, analyzed the design concept of The Electronic Chart software design and the function it will realized. Build the modularization program construction. The software design contains the navigation information management block, Electronic Chart block, sonar information block, database and the interface block. Finally, debugged the software to achieve the anticipated function.The design was based on the Visual C++ 6.0 developing platform, developed with the Microsoft Foundation Library (MFC) technology combined with the MapX components technology, managing the database on the open database connectivity (ODBC) technology, and finished the communication on serial interface.更多还原
