摘要
论文从雷达的探测性能角度,研究虚拟战场上雷达探测范围的可视化表现。在
简要介绍了本课题研究的背景和意义后,本文简略阐述了作战仿真系统的整体设计
架构,并结合工作重点详细讨论了虚拟作战仿真系统中情报分析子系统的设计与实
现。
论文首先建立了情报分析系统的数学模型,研究了雷达波在自由空间的传播衰
减模型,给出单基地雷达的作用距离方程,对有源噪声干扰进行了一定程度的探究;
建立雷达探测范围的数学表现模型,将无形的雷达波束通过几何模型有形的展现出
来,用于绘制雷达垂直平面探测范围图。
在前面的数学模型基础上,详细讲述了用 OpenGL 设计与实现情报分析系统的
过程。情报分析系统通过各个不同角度的 2D、3D 视图全面展示雷达的探测性能,
并显示战场环境中空间任一点的信号频谱图。
最后论文给出了情报分析系统的工作效果,对工作进行了总结与展望,提出进
一步需要改进的地方。

Abstract
This paper researches on the visualization of radar detection range in virtual
this paper,after briefly introducing the research background and
significance,it summarily presents the whole platform architecture of the bat
Simulation to what I have done in this project, this paper presents in
detail how to design and implement the Intelligence Analysis System.
First of all,this paper proposes the algorithm and mathematical models of the radar
wave:the mathematical model of the radar wave path loss in the free space is studied;and
the radar range equation of single-base radar is given;it also does some research on the
impact of active noise jamming;the mathematical representing model of radar detection
range is established,and the geometry model of radar beam is constructed.
Based on the mathematical model above,this paper describes in detail the design and
implementation of the Intelligence Analysis prehensively
displays the radar detection performance through 2D and 3D views,and also shows the
signal frequency spectrum of any point in the space of battlefield environment.
In the end, this paper shows the working effect of the Intelligence Analysis System in
the bat Simulation System,and it also sums up the future work and
prospects,putting forward for improvement.
