摘　　要：随着雷达重频和显示器显示分辨率的提高,当前VRAM的速度已经不能满足雷达视频的实时刷新要求。针对该问题,本文提出一种采用滚动输出模式的视频输出处理方法。通过实验验证,该方法在保证高数据率和高分辨率的前提下实现了雷达视频画面流畅刷新。With the improvement of radar repetition frequency and the display resolution, the speed of the current VRAM cannot satisfy the requirements of the real-time refresh of radar videos. A video output processing method based on the rolling output mode is proposed to solve such problem. It is verified through the test that under the premise of high data rate and high resolution, radar video images can be refreshed smoothly via this method.
