摘要:
采用通用计算图形处理器实现软件化雷达视频显示处理是雷达终端重要的技术方向之一。雷达视频带宽的激增对软件化雷达视频显示处理提出了新的挑战,目前国内外对大带宽雷达视频的显示处理还未能给出有效的解决方法。该文分析该项技术的瓶颈,创新性地提出了一种基于视觉无损压缩的雷达视频显示预处理方法,并进行了工程实现与验证。该预处理方法大幅降低了视频数据传输带宽和处理器资源占用率,提高了软件化视频显示处理的技术指标,提升了雷达终端的稳定性,为大带宽雷达视频的软件化显示处理提供了有效途径。
Abstract:
The software radar video display processing based on general purpose graphic processing units is an important technical development direction of radar terminal. The surge in radar video bandwidth has brought a new challenge for software radar video display processing. At present,there is no effective solution for large bandwidth radar video at home and abroad. Some bottlenecks of the technology are analyzed. A radar video display preprocessing method based on visual lossless compression is creatively proposed. An engineering is realized and verified. The preprocessing method dramatically reduces transmission bandwidth of video data and graphic processing units utilization. More importantly,the technical specifications of software video display processing and the stability of radar terminal are effectively improved. It provides an effective way for software display processing of large bandwidth radar video.
