| 摘 要： | 海上溢油给海洋生态环境带来严重的影响,快速准确地探测溢油对于防灾减灾具有重要的意义。利用卫星遥感探测溢油已成为目前主要的检测手段,大多采用合成孔径雷达(SAR)数据,运用图像处理的方法,开展了多种溢油提取算法的研究,取得了较好的结果,但由于海洋的类溢油现象存在,造成提取信息的精度达不到要求。近年来,国内外运用极化SAR数据开展溢油信息提取研究,从极化分解与相位差等角度对溢油特性分析,能有效地区分一些类溢油现象,得到了较理想的结果。分析了应用SAR数据开展溢油信息提取的研究状况,总结了溢油极化SAR探测的研究,指出了目前研究中存在的不足,并提出了今后溢油极化SAR遥感监测的方向。

| Abstract: | Oil spill brings the serious influence to marine ecological environment,fast and accurately detecting the oil spill is of great significance for disaster prevention and mitigation. By making use of satellite remote sensing for the oil spill detection has become the main means of detection,Using the SAR(synthetic aperture radar) data and image processing methods,most scholars carry out a variety of oil spill extraction algorithm research,and get some good results,but there exist some look-alikes,which affect the extract information accuracy. In recent years,from polarization decomposition and a phase,using polarization SAR data in oil spill information extraction,such as the oil spill characteristic analysis,can effectively distinguish between some kind of oil spill phenomenon,and obtain the ideal results. The application of SAR data is analyzed in the oil spill information extraction research,summarized the oil spill polarization SAR detection research is summarized,and the current of the insufficiency in research is pointed out,and the future oil spill polarization SAR remote sensing monitoring. |
