In this paper, the multi-baseline echo data was obtained by GB-SAR(Ground Based SAR) in IECAS which has a total of 101x161x96 (Elevation X Azimuth x Range) voxel(after range gating), we first padded the multi-baseline echo data with zero in every dimension to a total of 512x512x128 (Elevation x Azimuth x Range) in order to use Base- 2 FFT. We first reconstructed 3D SAR image with 3D range migration algorithm on Intel Xeon E5620 @2.40 GHz platform. Then, we use NVIDIA Tesla CI060 to reconstruct 3D SAR image with the same imaging algorithm. With Tesla CI060 we obtain 167X speedup ration compared with Intel Xeon E5620 CPU.
