GPU加速下脉冲压缩雷达的点迹凝聚
Acceleration of Pulse Compression Radar's Plots' Agglomerating on GPU
摘要
Abstract
GPU has the rather high video memory width and a mass of parallel calculating units. With the advance of GPU's programmability, GPU is used in common computing other than image manipulation. The acceleration of pulse compression Radar plots agglomerating by GPU's powerful compute performance is studied. At first, coarse grain parallelization that each target agglomerating ran on one CUDA threads is introduced, but the result showed that plots' processing time increases. Then the causation of the result is analyzed, and parallel scale is enlarged by parallelization of agglomerating process inside each target. New result shows that large scale & fine grain parallelization could make full use of GPU's powerful compute capacity and accelerate pulse compression Radar s plots agglomerating.关键词
