N2 - In this work, a new interpolation-free fast Range-Doppler (RD) Synthetic Aperture Radar (SAR) algorithm has been developed using parallel processing on Graphical Processing Unit (GPU). Our main aim is increasing the performance of the RCMC step of RDA algorithm. Interpolation is the most used algorithm in order to realize RCMC process. But, the 2-D complex valued interpolation on RCMC step produces some computation errors and also needs extra processing because of the ambiguous search operations. In our work, we have developed Parallel- Discrete Fourier Transform (P-DFT) algorithm as an alternative to interpolation. We have performed P-DFT and Inverse Fast Fourier Transform on GPU respectively to get rid of the interpolation process. We have implemented interpolation and P-DFT algorithm in parallel on both CPU and GPU. Our tests show us the proposed algorithm provide us fast and more accurate results while processing RCMC step.
