光栅扫描显示器上实现PPI雷达长余辉仿真

A implementation of PPI Radar Persistence simulating on raster scanning display

传统PPI雷达显示器中的长余辉消隐是计算机仿真雷达显示逼真与否的关键技术之一 ,其中数据显示的实时性又是仿真系统的主要性能指标。该文提出一种利用光栅扫描显示器上实现PPI雷达长余辉仿真的方法 ,这种方法采用Direct Draw、Win3 2技术 。

The issue of PPI Radar Persistence simulating is the most important technology and the basic performance of the simulating system is a key factor of he real time as simulating traditional PPI radar indicator on raster scan display. A PPI Radar Persistence simulating way on raster scan display is presented in this paper. The way applies DirectDraw and Win32 technique, the result of simulation is realistic and real time.
