摘　　要：分析了目前基于光栅显示器模拟雷达余辉的方法。针对实现逼真余辉效果存在的主要瓶颈,通过采用CUDA技术可以解决模拟余辉时庞大的计算量的问题。主要采用CPU+GPU的编程模式模拟余辉,在GPU中为每一个像素点创建一个并行执行的线程来完成整个屏幕像素的数据处理,使得余辉效果逼真、画面流畅、扫描速度大幅提高。Raster-scan based persistence vision simulative methods are analyzed in this paper,and the choke point of those methods is presented.Based on CUDA simulative method,the problem of gigantic data operation could be solved easily.CPU＋GPU programme method is adopted to simulate radar persistence vision,thread is created to deal with the data operation for each pixel which executes at the same time.Vivid persistence display and fluent image are got,and the scan speed can be promoted greaterly.
