Synthetic aperture radar(SAR)is a kind of active earth-observation system, which can produce high-resolution image all day and it has been widely used in agriculture and military. However, SAR image is affected by speckle due to the coherent imaging mechanism. In this paper, we propose a SAR image denoising algorithm based on generative adversarial network.We constructed the generated network by the structure of deep convolutional neural network(DCNN)with residual structure. The new generated network can accelerate the training process and improve the denoising performance. We also define a loss function by combining PSNR and SSIM, which makes the denoising result of SAR noisy image more in line with the visual perception requirements of human eyes. The experiment results show that the proposed algorithm can suppress speckle in SAR images and get good denoising result.
