Abstract

Abstract:

HJ-1C is the first civil S-band synthetic aperture radar(SAR) satellites launched by China, and the equipped SAR has the traits of all-weather, all-time, and penetrability. We focus on HJ-1C satellite. As SAR satellites have complex imaging algorithm and need large amount of calculation, we propose GPU-based SAR real-time imaging system based on GPU-based parallel processing technology. The results show that the processing speed of the SAR real-time imaging system is higher than 600 Mbps, meeting the real-time imaging processing requirements for practical SAR satellite ground receiving system.

Key words: HJ-1C, GPU, SAR, CS, CUDA
