AIR-SARShip-1.0：高分辨率SAR舰船检测数据集

AIR-SARShip-1.0: High-resolution SAR Ship Detection Dataset

近年来,深度学习技术得到广泛应用,然而在合成孔径雷达(SAR)舰船目标检测研究中,由于数据获取难、样本规模小,尚难以支撑深度网络模型的训练。该文公开了一个面向高分辨率、大尺寸场景的SAR舰船检测数据集,该数据集包含31景高分三号SAR图像,场景类型包含港口、岛礁、不同级别海况的海面等,背景涵盖近岸和远海等多样场景。同时,该文使用经典舰船检测算法和深度学习算法进行了实验,其中基于密集连接端到端网络方法效果最佳,平均精度达到88.1%。通过实验对比分析形成指标基准,方便其他学者在此数据集基础上进一步展开SAR舰船检测相关研究。

Over the recent years,deep-learning technology has been widely used.However,in research based on Synthetic Aperture Radar(SAR)ship target detection,it is difficult to support the training of a deep-learning network model because of the difficulty in data acquisition and the small scale of the samples.This paper provides a SAR ship detection dataset with a high resolution and large-scale images.This dataset comprises 31 images from Gaofen-3 satellite SAR images,including harbors,islands,reefs,and the sea surface in different conditions.The backgrounds include various scenarios such as the near shore and open sea.We conducted experiments using both traditional detection algorithms and deep-learning algorithms and observed the densely connected end-to-end neural network to achieve the highest average precision of 88.1%.Based on the experiments and performance analysis,corresponding benchmarks are provided as a basis for further research on SAR ship detection using this dataset.
