Abstract: Synthetic Aperture Radar (SAR) is an indispensable remote sensing technology nowadays. However, due to the different imaging theory applied in Synthetic Aperture Radars, the interpretation of SAR images may come out as extremely different from conventional optical satellite images. Thus, to tackle with the interpretation problem, a specialized SAR-optical image translation model is developed to directly translate the original SAR images into equivalent optical satellite images. This model is implemented with a novel two-step Generative Adversarial Network architecture. To present the performance of proposed model on SAR-Optical image translation task, remote sensing data acquired from Sentinel-1 and Sentinel-2 is utilized for the model training and validation phase. The final results indicate a promising performance both on enhancing the human perception of translated optical images and increasing the statistical indices of PNSR and SSIM, which have reached at 19.09 dB and 0.4211 respectively.
