摘要
论述了海洋油气藏烃类渗漏在海洋表面形成的浮油膜特征，并讨论了海面油膜的存在对海面短重力波的影响和海洋合成孔径雷达（ＳＡＲ）图像的后向散射系数σ°的调制，及油膜在ＳＡＲ图像上的特征，探讨了对ＳＡＲ图像进行处理以降低雷达斑点噪声，增强图像上油膜特征的方法。指出了ＳＡＲ图像用于检测海面油膜的可行性。试图建立利用ＳＡＲ图像检测海洋油气藏烃类渗漏形成的海面油膜的依据。
The paper discusses the characteristics of oil slicks caused by hydrocarbon seepage of natural submarine oil and gas deposits,and the effect of sea surface short gravity wave and the modulation of back scattering coefficient σ° resulting from sea surface oil slicks.The characteristics of oil slicks in SAR images and the methods of image processing to reduce the radar speckle noise and enhance the oil slicks′ characteristics are presented.At last,the authors point out the feasibility of sea surface oil slick detection using SAR images and try to establish the detecting evidences of sea surface oil slicks aroused by hydrocarbon seepage.
