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.
