摘要
雷达屏幕仿真是雷达系统仿真的重点和难点.文章在讨论OpenGL和分形算法的基础上,进行雷达显示器仿真.采用荧光指数衰减曲线方程建立余辉亮度衰减数学模型,实现余辉效果.运用分形插值算法生成高程数据,进行平滑处理,在对高程数据着色后利用OpenGL纹理映射技术绘制地形到雷达屏幕,实现了雷达屏幕和地形的结合.
The simulation of radar display wave is emphases and difficulty in radar simulation system. That how to simulate radar display based on OpenGL and fractal algorithm is discussed. Mathematical model of brightness weaken is established by using the fluorescence exponential decay curve equation and the s brightness effect is realized. Creating elevation data with fractal interpolation algorithm and smoothing treatment is done. Terrain is protracted to radar display after coloration with texture mapping technique of OpenGL and then the coalescent of radar display and terrain is achieved.
