Abstract :
Parallelization based on general purpose graphic processing unit (GPGPU) is a kind of promising technology widely used to improve the computing performance. GPU is designed for data parallel and computational intensive applications. In this paper, a d ata processor based on multiple GPGPU devices is propo sed for SAR signal processing. Some key technologies are emphasized for exploiting the best performance of GPGPU. And t he processor´s performance is demonstrated by the implementation of range-Doppler imaging algorithm, which shows it is suitable for real-time SAR signal processing.
