摘　　要：为了实现机载雷达训练模拟器人机交互界面,对雷达模拟器PPI显示进行设计。为了获取更逼真的实时显示,首先对雷达模拟器PPI显示的构成进行分析,设计字符显示模块和图形显示模块,然后介绍了模拟器中PPI显示的关键技术问题及解决途径,包括雷达点迹显示、杂波目标显示以及扇扫显示,采用颜色等级亮度不同来显示扫描更新的点迹,用具有某种特定概率密度和自相关函数产生随机数方法来近似仿真杂波目标显示。将改进方法应用于某型机载雷达训练模拟器中,取得了良好效果。In order to better achieve the airborne radar training simulator interactive interface,it is necessary to research the PPI display of radar simulator to simulate more realistic display pictures.In the paper,first,we analysed the composition of the radar simulation systems and the display pictures of PPI,and designed character display and graphic display modules.Then we discussed and designed the key technology of radar simulation about the radar point tracking display,the clutter and target display,and the sector scan display.The update point tracking was displayed by the difference grade and brightness of color.The method of generating random numbers was used to approximate simulation clutter and target display with a certain probability density and autocorrelation function.At last,the method has been applied in the airborne radar simulator,and proved effective in practice.
