An Efficient Signal Processor of Synthetic Aperture Radar Based on GPU

Abstract:
The extending of Synthetic Aperture Radar (SAR) applications brings new challenges to SAR signal processing. Highly efficient SAR signal processors need to be explored towards these challenges. Recently, Graphics Processing Unit (GPU) is developing at top speed, which is a novel and promising computation platform for efficient SAR processors. A GPU-based SAR signal processor is introduced in this paper. The implementation of this processor takes full advantage of GPU’s computation capability. This processor is more than ten times as fast as traditional CPU-based SAR processor. It provides a promising way to solve the problems of SAR signal processing in the future.
