Underwater turbulence affects optical imaging primarily through speckle, blurring, and distortion caused by phase disturbances in light waves during propagation, which severely limits the application of traditional imaging methods in underwater environments. The phase screen model can effectively simulate the impact of underwater turbulence on light propagation, providing a simulation foundation for the study of imaging technology under turbulence conditions. Correlation imaging technology, with its ability to detect targets indirectly, high sensitivity to weak light, and strong anti-interference capabilities, shows extensive potential in turbulent environments. This study combines the turbulence phase screen model with three correlation imaging methods based on Hadamard matrices (traditional method, wavelet transform method, and cake-cutting method), systematically comparing their imaging performance under different turbulence intensities. Subsequently, to further improve image quality, the blurred images obtained through turbulence correlation imaging are input into a conditional generative adversarial network for denoising and restoration, exploring the feasibility and advantages of artificial intelligence in optimizing underwater turbulence imaging. The experimental results demonstrate that the combination of deep learning and correlation imaging significantly improves imaging quality in turbulent environments, providing an efficient solution for practical underwater optical imaging applications. %K 水下湍流， %K 关联成像， %K 深度学习， %K 去模糊， %K 生成对抗网络
