基于CUDA的高速雷达回波显示技术

High-speed Radar Echo Display Technology Based on CUDA

针对场面监视雷达高转速的要求,提出了一种基于CUDA并行化编程的高速雷达回波显示技术。该技术将CUDA和DirectX相结合,通过CUDA技术提高了回波显示和余辉绘制的速度,通过DirectX技术实现了回波画面和其他辅助信息的叠加。该技术已在某型场面监视雷达中得到应用,运行结果可以满足该场面监视雷达60r/min的高转速需求,显示画面清晰连贯,且支持缩放和漫游等操作。

According to the demands of high rev of surface movement radar （SMR）,this paper pres- ents a technology of fast radar echo display based on CUDA parallel programme. The technology combines CUDA with DirectX,increases the speed of radar echo display and afterglow drawing by CUDA technology, realizes superimposition of echo drawing and other assistant information through DirectX technology. The technology proposed in this paper has been applied to some type of SMR,and the running results can satisfy the high rev requirement of 60 r/min of this SMR, at the same time the display drawing is clear and continuous and operations such as zoom, cruise, etc. are provided.
