A Radar Signal Processing Method Based on CPU+GPU Hybrid Architecture
Aiming at the complexity trends of the radar system,a signal processing method based on CPU+GPU hybrid architecture is proposed.According to the computational complexity,the fine granularity division of task is performed,and the complicated processing task is decoupled into two parts of logic processing and operation processing and mapped into CPU+GPU cores to be processed.According to the unpacking,pulse compressing,coherent-integration,target detection,post-processing of target detection and ambiguity resolution of radar signal process,the corresponding processes are mapped into CPU+GPU cores to improve the acceleration ratio.The experiment results show that the proposed method has better performance than the multi-core DSP signal processing method.
