机载雷达训练模拟器PPI显示的建模仿真

Modeling and Simulation of PPI Display of Airborne Radar Training Simulator

针对机载雷达PPI显示进行了建模仿真研究,机载雷达PPI主要显示目标、杂波、自检画面、扇区、电子地图、海岸线和各种战术或地面标志符号等。采用VC++语言开发,模块化设计,通过建模仿真,解决了机载雷达模拟器PPI显示实现中的四个难点:自检画面显示、扇区设置、运动目标显示和杂波显示,最终仿真结果证明所建模型拟合度好,能为雷达操作员提供逼真的PPI显示画面,可以达到或接近实战中才能得到的训练效果。

Modeling and simulation of airborne radar PPI display were studied.Airborne radar PPI display contains target,clutter,display of BIT,sector,electronic map,coastline and signs of tactics.It was developed by VC＋＋.It solved four difficulties of PPI of airborne radar simulator by modeling and simulation： display of BIT,setting of sector,display of moving target and display of clutter.The simulation has been proved effective in practice.It can provide realistic display of PPI for radar operator and reach well effect in battle.
