The Simulation of Radar Display Based on OpenGL

雷达显示器仿真是雷达系统仿真的重点和难点。在简要介绍OpenGL技术和雷达显示器的基础上,提出了利用OpenGL对P型雷达显示器进行仿真的思想,详细介绍了余辉扫描和目标点迹的仿真方法。对于余辉扫描,通过数学建模提出了实现途径,并得出了时间衰减常数和扫描周期的计算公式。对于目标点迹,提出了角度换算和目标位置的计算公式,并实现了点迹的余辉效果。结果表明,该方法达到了很好的仿真效果。

The simulation of radar display is important and difficult in the simulation of radar system. On the basis of briefly introducing OpenGL and radar display, this paper proposes the simulation idea of Ptype radar display using OpenGL, and introduces the simulation method of brightness scan and object dot in detail. For brightness scan, the paper proposes implementation means via mathematics modeling, and deduces the computation formulas of time attenuation constant and scan period. For object dot, it deduces computation formulas of angular conversion and object position, and realizes the dot brightness. The results show that the method proposed achieves a good simulation effect.
