摘要: 冬季海冰会极大影响辽东湾地区近岸工程建筑、石油平台、船舶航行等安全生产活动。星载合成孔径雷达不受天气影响且分辨率高，可用于辽东湾海冰灾害监测。本文在深度学习模型UNet++的基础上引入卷积注意力模块（CBAM），并使用交叉损失函数来优化模型，建立辽东湾Sentinel-1 SAR图像高精度海冰检测模型（AUNet++），并与PSPNet、Deeplabv3+、DAU-Net等多种深度学习方法进行对比。实验结果表明AUNet++海冰检测方法在OA、AA、MIoU、Kappa系数4种指标上分别达到了97.56%、97.53%、95.19%、95.07%，结果优于其他深度学习方法。该方法可以在高风速的干扰下对海冰边缘、光滑冰面完成精确海冰信息提取，能够为辽东湾地区的大范围、高精度海冰检测工作提供技术支撑。

Abstract: The sea ice in Bohai Sea in winter affects the safety production activities of oil platform and ship navigation, as well as the safety of offshore engineering and construction. Spaceborne SAR is not affected by weather and has high resolution, which can be used for sea ice disaster monitoring in Bohai Sea. Based on deep learning model UNet++, this paper introduces Convolutional attention module (CBAM) and uses cross loss function to optimize the model, and establishes a high-precision sea ice detection model for Sentinel-1 SAR data in the Liaodong Bay (AUNet++). And compared with PSPNet, Deeplabv3+, DAU-Net and other deep learning methods. The experimental results show that AUNet++ sea ice detection method achieves 97.56%, 97.53%, 95.19% and 95.07% in OA, AA, MIoU and Kappa coefficients, respectively, which is superior to other deep learning methods. This method can extract accurate sea ice information from sea ice edge and smooth ice under the interference of high wind speed, and can provide technical support for large-scale and high-precision sea ice detection in Liaodong Bay area.-
