| Abstract: | The research focus on high-performance computing technology based on the third generation GPU of NVIDIA CUDA (Compute Unified Device Architecture).Pulse compression radar data processing algorithms including of pulse compression and coherent accumulation have been realized by using GPU GTX470 which has 448 processing core. According to GPU parallel processing architecture, algorithms of pulse compression and coherent accumulation have been optimized and mapped to the 448 processing core of GPU TTX470 effectively, the pulse compression radar processing algorithm has been implemented based on GPU, the result and processing real-time performance have been evaluated. |
