Range Cell Migration Correction (RCMC) is a key step in the imaging procedure of Synthetic Aperture Radar (SAR). The performance of RCMC affects the final SAR image quality greatly. Traditionally, RCMC is carried out via an interpolation operation on CPU, and is a time-consuming phase in the whole processing flow. In this paper, a novel RCMC technique using texture mapping is proposed. The texture mapping operation is implemented on the Graphics Processing Unit (GPU), which accelerates the operation by special hardware structure. The proposed RCMC technique can achieve a higher speed compared with the traditional methods designed for CPU.
