Range-Doppler Algorithm (RDA) and Chirp Scaling Algorithm (CSA) are two widely used Synthetic Aperture Radar (SAR) imaging schemes. Both require multiple transpose operations which increase the total processing time significantly. In this paper, we propose transpose-free flow for both RDA and CSA. This is achieved by modifying the existing flows in order to utilize the access patterns favored by the external memory. As a result, the peak performance of the memory is sustained and the processing time shortened. The proposed Field Programmable Gate Array (FPGA)-based implementation outperforms the existing SAR accelerators; it computes RDA and CSA on data size of 4, 096 x 4, 096 in 323ms and 162ms, respectively. |
