Abstract :
The proposed method is devised to reconstruct a focused radar image for a wide observation angle without an interpolation, and therefore, it improves the image quality and reduces the processing time. To evaluate the performance, it is compared with the conventional sampling method through simulation and experimental results. In the case of the proposed method, the computation time is improved more than 33% for the image size of 1024×1024 pixels
