在这项研究中，双极化合成孔径雷达（SAR）测量被用来加强溢油观测。建立了海面溢油和生物浮油的共极化相位差（CPD）模型，并将其用于描述海面溢油和生物浮油的散射回波。该模型预测，在低到中等风力条件下，石油相对于海洋的CPD标准差较大（），而生物浮油的CPD标准差与海洋的CPD标准差相似。完成与多视复杂（MLC）的C-和L-波段SAR数据的实验表明，该模型的预测得到证实，C-波段，如预期的那样，是首选的L-波段。
In this study dual-polarized synthetic aperture radar (SAR) measurements were used to enhance oil spill observation. The co-polarized phase difference (CPD) was modelled and used to characterize the scattering return from oil spills and biogenic slicks. The model predicts, under low to moderate wind conditions, a larger CPD standard deviation () for oil with respect to the sea, while for biogenic slicks a value similar to that for the sea is obtained. Experiments accomplished with multilook complex (MLC) C- and L-band SAR data show that the model predictions are confirmed and that the C-band is, as expected, to be preferred to the L-band.
