海底油渗SAR探测综述

Oil Seep Detection Using SAR Image

海底油渗来源于海底石油的自然渗漏,及时地获得海底油渗信息对探测、开发海底石油资源具有重大意义。目前,合成孔径雷达(Synthetic Aperture Radar,SAR)已经成为海底油渗探测的新型辅助手段。首先总结了海底油渗SAR探测机理,包括海底油渗形成机制、海底油渗SAR成像原理和海底油渗SAR图像特征;其次介绍了海底油渗SAR探测方法;然后给出了目前国际上海底油渗SAR探测的应用现状;最后提出了海底油渗SAR探测的现存问题和未来发展方向。

Oil which naturally leaks to the sea-surface from seabed is called oil seep.Oil-seep information is very important to detecting and exploiting seabed oil resource.At present,SAR has become a new supplementary method for seabed oil detection.In the paper,the detection mechanisms of oil seep were summarized,including the formation mechanism,SAR imaging principle and the SAR image features.Then,the detection method and the application were introduced.At last,the existing problems and the development direction were put forward.
