【摘要】:战场电磁环境的研究一直备受各个国家重视,正是因为电子战在世界范围内越来越多的被用于战场上,也屡建奇功。干扰、迷惑、诱导、欺骗,各式各样的辐射源在战场上扰乱着战争双方的“眼睛”,区分并发现真实目标是在战场上占据主导地位的关键。本文首先构建了辐射源模型、无源干扰模型,并利用当今效率较高的瞬时自相关算法进行信号分选与识别,并针对实际应用按需求编写了仿真软件。本文的主要工作和贡献如下:(1)简要介绍了战场电磁环境仿真在现在化战场上的重要地位,分析了目前国内外机构、专家对于电磁环境仿真的研究现状,并阐述了本课题的研究意义。(2)构建了辐射源信号,包括各式发射信号及回波信号。建模对象包括均匀脉冲串信号、线性调频信号、捷变频信号、目标回波信号、杂波以及接收机噪声。(3)建立MFC控件窗口结合OpenGL的绘图框架,以此绘制辐射源及辐射范围;引入MapX二维地图,并对其进行二次开发,实现了在中国及近海范围内的电磁环境显示,并参考结合了MapX提供的开发文档,利用其API对地图上的功能进行了进一步改良和优化,为整个系统提供良好的人机交互打下了基础,完成了电磁环境仿真可视化显示。(4)在设计系统时综合利用中介者模式、观察者模式以及单例模式等设计模式,编写出易维护、易扩展、易复用、灵活性好的程序,在面向对象编程中降低了模块间耦合性,在一定程度上优化了代码。(5)设计装备载体数据库,利用微软提供的ADO接口,在VS 2010中实现了连接关系型数据库SQL Server 2008 R2,并利用VS中读取字符串的形式读取SQL语句,完成了在MFC框架下对装备载体数据库的增删改查等操作。
[Abstract]:The study of battlefield electromagnetic environment has been paid much attention by many countries. It is precisely because more and more electronic warfare is used in the battlefield all over the world. Interference, confusion, inducement, deception, and various sources of radiation disturb the "eyes" of both sides of the war on the battlefield, distinguishing and discovering that real targets are the key to dominating the battlefield. In this paper, the emitter model and the passive interference model are first constructed, and the efficient instantaneous autocorrelation algorithm is used for signal sorting and recognition, and the simulation software is written according to the needs of practical applications. The main work and contributions of this paper are as follows: (1) the important position of battlefield electromagnetic environment simulation in the present battlefield is briefly introduced, and the current research status of electromagnetic environment simulation at home and abroad is analyzed. The significance of the research is also expounded. (2) the emitter signal is constructed, including all kinds of emitter signal and echo signal. The modeling objects include uniform pulse train signal, linear frequency modulation signal, agile frequency conversion signal, target echo signal, clutter and receiver noise. (3) the drawing frame of MFC control window combined with OpenGL is established to draw emitter and radiation range; The MapX two-dimensional map is introduced and redeveloped to realize the display of electromagnetic environment in China and offshore areas. With reference to the development documents provided by MapX, the functions on the map are further improved and optimized by its API. It lays the foundation for the whole system to provide good human-computer interaction, and completes the visualization display of electromagnetic environment simulation. (4) in the design of the system, the intermediary mode, the observer pattern and the singleton pattern are used to design the system. The program is easy to maintain, easy to expand, easy to reuse and flexible. It reduces the coupling between modules in object-oriented programming, and optimizes the code to some extent. (5) Design equipment carrier database, utilize the ADO interface provided by Microsoft, The connection relational database SQL Server 2008 R2 is implemented in VS 2010, and the SQL statement is read in the form of reading string in VS. The operation of adding and deleting the equipment carrier database under the MFC framework is completed.
