Abstract
Parallel processing is an effective way to process Synthetic Aperture Radar (SAR) data quickly and realize realtime imaging. Based on the traditional serial Range-Doppler algorithm, a parallel SAR imaging processing scheme is present by using of pipeline technology, and partition approach of computing nodes in both range and azimuth compression is discussed. Computing results show that, when the ratio of nodes is 2/4 or 2/5, the efficiency of parallel processing can be satisfied, in which 2/4 refers to the best efficiency and 2/5 to the best speedup. The ability of real-time SAR imaging is also tested, from which the ultimate computing time of a frame image is about 0.5 s, smaller than the forming time of 0.92 s.
