基于OpenGL的雷达PPI显示器仿真方法

The Simulation Method of Radar PPI Display based on OpenGL

雷达显控终端作为对雷达数据的直观表述,是各种雷达系统中的重要组成部分。在对雷达显控终端进行模拟仿真时,其实现的困难在于对雷达PPI显示器的逼真模拟。为了较好地解决此问题,首先对OpenGL和雷达显示器进行了简要概述,在此基础上,提出了一种新的基于VC++和OpenGL的具有余辉效果的雷达PPI显示器仿真模型及其实现方法。方法简单灵活、易于掌握,模块通用性和可扩展性强,可移植性高。与实装雷达PPI显示器余辉效果的对比以及实际应用证明,该仿真模型及方法达到的仿真效果符合工程要求,具有较高的实用价值。

Radar display terminal is used to intuitionally display the radar information,which is an important component of different kind of radar system,at the same time,the vivid simulation of radar PPI display is a difficulty in the simulation of radar system.To solve the problem better,the radar display and OpenGL are first briefly described in the paper,and then a new simulation model and method of radar PPI（Plan Position Indicator）display with brightness based on VC＋＋ and OpenGL are presented.The method is simple and easy to be grasped,the module can easily be reused,expanded and transplanted.The comparison between the simulation results and the results of real radar display and the actual applications show that it is fit for project needs and has the certainly practical value.
